The Ruby Princess cabins to avoid are mostly a question of location rather than category: cabins on Riviera deck (14) that sit under the Lido deck pools and buffet, obstructed-view oceanview cabins, cabins at the far forward and aft ends if you are prone to seasickness, and cabins next to busy lifts, stairwells or service areas. The best cabins for most people are midship balconies on the middle decks, especially the larger half-covered balconies on Caribe deck (10).
Ruby Princess is a 113,561-ton, 3,080-guest ship with 1,542 cabins, and it is sailing from San Francisco through 2026-27 on California Coast, Mexican Riviera, Hawaii, Pacific Northwest and Alaska itineraries. Because she does a lot of open-Pacific sailing, where your cabin sits matters more than on a calm Caribbean route. This guide covers every cabin type, from inside cabins to balconies. If you are thinking about a mini-suite or full suite, our companion Ruby Princess suites and mini-suites guide covers those in detail.
Ruby Princess cabins at a glance
Ruby Princess is a Crown-class ship, a stretched version of the older Grand-class design. Cabins run from deck 5 (Plaza) up to deck 15 (Lido), and Princess calls them staterooms. Here is how the main categories compare, using the sizes Princess publishes.
| Cabin type | Number on board | Typical size | Best for |
|---|---|---|---|
| Interior | 436 | 158-162 sq ft | Budget cruisers, light sleepers who want total darkness |
| Oceanview | 218 | 146-206 sq ft | Natural light without paying for a balcony |
| Balcony | 682 | 214-222 sq ft including balcony | Most couples, scenic cruising in Alaska and along the coast |
| Mini-suite (incl. Reserve Collection) | 178 | About 323 sq ft including balcony | More space, a sofa bed for a third guest |
| Suites and family suites | 26 suites plus 2 family suites | Roughly 460 sq ft and up including balcony | Longer cruises, families, suite perks |
Around 80% of outside cabins have a private balcony, so even at the lower end of the balcony price range you have plenty of choice.
Ruby Princess cabins to avoid
None of the cabins on Ruby Princess are bad in themselves. The problems people run into almost always come from what is above, below or next to the cabin. These are the locations worth thinking twice about.
Riviera deck cabins under the Lido deck
Riviera deck (14) is the deck directly below Lido (15), where the main pools and the World Fresh Marketplace buffet are. Cabins here have covered balconies and are close to food and sun, but some guests report hearing deck chairs being moved and cleaning crews working early in the morning, and pool deck noise late in the evening. Other guests on the same deck hear very little, so it varies cabin to cabin. If you are a light sleeper, choose a deck that has cabins above and below you instead, such as Baja (11) or Aloha (12).
Obstructed-view oceanview cabins
Princess sells some oceanview cabins as obstructed (category codes OV, OW, OY and OZ). Most are on Emerald deck (8), where the lifeboats hang outside the windows, and there are a few on Lido deck (15). The level of obstruction varies a lot: some cabins have a partial view past a lifeboat, while others look straight at one. If the price gap to an unobstructed oceanview is small, it is usually worth paying it. If all you want is daylight, an obstructed cabin can still be a sensible saving.
Cabins near lifts, stairwells and service areas
Cabins right beside a lift lobby or main staircase are convenient but can get corridor chatter late at night and early in the morning. Cabins near crew doors, service lifts or galley areas can get trolley and door noise at odd hours. Cabins next to the self-service launderettes see steady foot traffic on sea days.
Cabins above or below loud public rooms
On the lower decks, look at what sits above or below your cabin. Cabins directly under or over the theater, casino, nightclub or main lounges can pick up music and rehearsal noise. Most cabin decks on Ruby Princess are sandwiched between other cabin decks, which is exactly what you want, but cabins at the edges of the public-room decks are worth a quick check.
Far forward and far aft if you get seasick
The ends of the ship move the most in a swell. On routes like the California coast, Hawaii crossings and Pacific Northwest cruises, open-ocean days can be lively. Forward cabins can also pick up anchor and thruster noise when the ship docks. If you are prone to seasickness, a midship cabin on a lower or middle deck is the safest choice.

Best cabins on Ruby Princess
When people ask about the best cabins on Ruby Princess, they usually mean the best value for a normal budget. These are the locations that tend to work well.
Caribe deck balconies (deck 10)
Caribe deck balconies are frequently recommended by regular Ruby Princess cruisers. On this deck the balconies are deeper than the standard ones and are partly covered and partly open to the sky, so you get more room and some privacy. The trade-off is that the open part can be seen from balconies higher up.
Midship balconies on Baja and Aloha (decks 11 and 12)
These decks have cabin decks above and below, covered balconies and a central position for motion. They make a good default if you just want a quiet, stable balcony cabin and do not want to study the deck plan for hours.
Aft-facing balconies
Aft cabins look out over the wake, and some aft-facing balconies on Ruby Princess are larger than side balconies. They are popular on scenic itineraries. The downsides are more motion in rough seas, a longer walk to the theater and forward lounges, and occasional engine vibration or wind. Good for good sailors, not ideal if you get seasick.
Interior and oceanview cabins on lower decks
If you are on a budget, a midship interior cabin on a lower deck is the most stable and darkest option on the ship. Plaza deck (5) has oceanview and interior cabins low in the ship, a good choice if you want stability and do not mind using the lifts.
Mini-suites and suites
Mini-suites on Dolphin (9) and Emerald (8) decks give you noticeably more space and a sofa bed for not much more than a balcony on some sailings. Note that Dolphin deck balconies are open from above, so they offer little privacy. For full comparisons, perks and which suites to skip, see our guide to Ruby Princess suites and mini-suites.
Avoid this, book that instead
| If you want to avoid | Book instead |
|---|---|
| Pool deck and buffet noise | A balcony on Baja (11) or Aloha (12) with cabins above and below |
| A lifeboat in your window | An unobstructed oceanview, or an interior cabin if you only need a bed |
| Seasickness | A midship interior or balcony on a lower or middle deck |
| Being overlooked on your balcony | A covered balcony on Baja, Aloha or Riviera deck |
| Corridor and lift noise | A cabin a few doors away from lift lobbies, stairs and launderettes |

How to check a Ruby Princess cabin before you book
This is the step most people skip, and it is the one that avoids most cabin complaints. Before you pay a deposit, do this:
- Find the cabin on the deck plan. Use the deck plans on princess.com or a free tool like the Ruby Princess cabin check on CruiseDeckPlans.
- Look one deck up and one deck down. You want cabins above and below you. Watch for the buffet, pool deck, theater, casino, nightclub or galley.
- Check either side. Look for lifts, stairs, crew doors, service areas and launderettes next to the cabin.
- Read the category code. Obstructed oceanview codes on Ruby Princess are OV, OW, OY and OZ. A balcony category description will often say whether the balcony is larger or partly open.
- Check the bed layout. Princess notes that in some cabins the twin beds cannot be pushed together into a queen. If that matters, ask before booking.
The guarantee cabin gamble
A guarantee fare (often shown as a category guarantee) is cheaper because Princess picks the cabin for you, at or above the category you paid for. You might get a great location, but you might also end up under the Lido deck, at the very front of the ship or with a partly blocked view in that category. If you are a light sleeper or get seasick, pay a little more to choose your exact cabin.
Which Ruby Princess cabins suit which travellers?
- Light sleepers: mid-deck balcony or interior cabins with cabins above and below, away from lifts.
- Seasick travellers: midship, as low as you are comfortable with. Avoid the forward and aft ends.
- Families: a mini-suite with a sofa bed, two connecting cabins, or one of the two family suites on Dolphin deck, which sleep up to eight.
- Alaska and scenic cruising: any balcony, but aft-facing and Caribe deck balconies are the most popular.
- Guests with limited mobility: Ruby Princess has 31 wheelchair-accessible cabins across suite, mini-suite, balcony, oceanview and interior categories. Midship cabins near the lifts cut down walking.
- Tight budgets: an interior cabin, with the money saved spent on a drinks package or a specialty dinner.
If you are comparing sister ships, the layout and advice are very similar on our Crown Princess cabins guide and Emerald Princess cabins guide, since all three ships share the same basic design.
Quick checklist before you book
- Is the cabin midship-ish, or are you comfortable with motion at the ends?
- Is there a cabin deck directly above and below?
- Is it at least a few doors from lifts, stairs and launderettes?
- If it is oceanview, is the category obstructed?
- If it is on Dolphin or Caribe deck, are you happy with a balcony that is partly visible from above?
- Have you checked whether the beds convert to a queen?
- Would a guarantee fare save enough to be worth the risk?
Prices for Ruby Princess sailings move around a lot, especially on repositioning and Pacific Northwest cruises. Our cruise deals for 2027 roundup is a good place to watch for offers once you know which cabin type you want.
FAQs
Which cabins should I avoid on Ruby Princess?
The main ones to avoid are Riviera deck (14) cabins directly under the Lido deck pools and buffet if you are a light sleeper, obstructed oceanview cabins (OV, OW, OY and OZ) if you want a clear view, far forward and aft cabins if you get seasick, and cabins right next to lifts, stairwells and service areas.
What is the best deck to stay on Ruby Princess?
For most people, the middle cabin decks are best: Caribe (10), Baja (11) and Aloha (12). They have cabin decks above and below, and a midship cabin there gives a good balance of stability and access to the rest of the ship.
Are Caribe deck balconies on Ruby Princess bigger?
Yes, many Caribe deck balconies are deeper than standard balconies and are partly covered and partly open. That gives you more space, but the open section can be seen from balconies above.
What does an obstructed balcony or oceanview mean on Princess?
It means something, usually a lifeboat or part of the ship’s structure, blocks some or all of the view from your window or balcony. On Ruby Princess the obstructed categories are oceanview cabins, mainly on Emerald deck (8), and the level of obstruction varies from cabin to cabin.
Where is the best place to stay on Ruby Princess to avoid seasickness?
Book a midship cabin on a lower or middle deck. That part of the ship moves the least. Interior or oceanview cabins on lower decks are the most stable, and a midship balcony on deck 10 or 11 is a good compromise.
