New Cruise Ship To Feature World’s Most Expensive Treehouse At Almost $90,000 Per Week

$90,000 a week for a cruise ship cabin sounds ridiculous at first.

But that’s almost what Royal Caribbean is charging for its brand-new Ultimate Family Treehouse on Hero of the Seas – a three-storey suite that’s unlike anything else at sea.

It’s part luxury villa, part over-the-top family playground, and it’s already shaping up to be one of the most talked-about cruise suites ever announced. The real question is… will anyone actually book it?

Because once you look at what’s included, it starts to feel a little less straightforward.

This Isn’t Just A Cabin – It’s A Three-Storey Treehouse At Sea

Royal Caribbean isn’t known for doing things by halves, and the Ultimate Family Treehouse is no exception. Set to debut on Hero of the Seas in 2027, this is one of the most ambitious suites the cruise line has ever created.

This isn’t just a bigger cabin with a theme. It’s a full three-level space designed to feel like its own private world onboard. It sleeps up to 12 guests, has four bathrooms, and includes everything from a games room to a rooftop terrace with a whirlpool.

It also says a lot about where cruise ships are heading. On Icon-class vessels, where you stay is becoming just as important as what you do.

In this case, it might end up being the main attraction.

Inside The Ultimate Family Treehouse

Step inside and the first thing you notice is just how liveable the space feels.

The main living area is designed as the heart of the suite, with big, comfortable sofas, a TV area for relaxing together, and a dining space where everyone can actually sit down at the same time. It feels much closer to a holiday apartment than a cruise cabin.

Upstairs is where things quieten down a bit. This is where you’ll find the two main bedrooms, each with their own private balcony and en-suite bathroom. They feel properly separated from the main social space, which makes a big difference on a busy family trip.

It’s not a complicated layout, but it’s a smart one. Everything has its place, and nothing feels like an afterthought.

But across both levels, there’s something else that really stands out.

The Teen Hideout Might Be The Smartest Feature

Rather than squeezing kids into spare corners, Royal Caribbean has given them a space that runs across two levels of its own.

It starts downstairs, where the games room connects directly to a twin bedroom. With table football and a gaming setup, it feels more like a hangout than somewhere you’re sent to sleep.

From there, a spiral staircase leads up to a second twin bedroom, along with a chill-out space and nearby bathrooms.

Put together, it’s basically a two-storey mini apartment within the suite.

And it even has its own staircase, separate from the main one. That might sound like a small detail, but it makes a huge difference. Teens can do their own thing without constantly drifting through the main living space.

If you’ve ever cruised with teenagers, you’ll know how big a win that is!

A Rooftop Terrace That Feels Like A Private Villa

At the very top of the treehouse is what might end up being the standout feature.

The rooftop terrace is a proper outdoor living space, not just a token balcony. There’s a private whirlpool, an outdoor dining area, and even a big-screen TV for evenings outside.

There’s also a mix of shaded areas and open sun loungers, which sounds simple but is actually a big deal on a cruise. You can use the space at any time of day without feeling like you’re baking or hiding.

It’s easy to imagine this becoming the spot where everyone naturally ends up – especially on sea days.

It Sleeps 12 – But Who Is It Really For?

Sleeping up to 12 guests sounds very kid-focused at first glance.

But it makes a lot more sense when you think about how people actually travel now.

Multi-generational trips are more popular than ever – grandparents, parents and kids all travelling together. Or even two families sharing one space. This layout works for that in a way most cruise accommodation doesn’t.

You can spend time together when you want to, but you’re not all on top of each other by day three.

That’s harder to achieve than it sounds.

The Design Is Completely Different To Anything Else Onboard

If you’ve seen Royal Caribbean’s Ultimate Family Townhouse on other Icon-class ships (and on Hero of the Seas – the Treehouse and the Townhouse are both on the same ship), you might be expecting something bold and theme park-like.

This isn’t that.

The Treehouse leans much more into natural, earthy design. There are wood-style finishes throughout, softer colours, and a calmer overall feel.

There are still playful touches – monkeys and other primates pop up here and there – but it doesn’t feel over the top.

It’s somewhere you could actually relax, which isn’t always the case with heavily themed spaces.

So… Why Is It So Expensive?

Let’s not pretend otherwise – around $87,500 per week is an eye-watering price.

Even in luxury travel terms, that’s right at the top end. For most people, it’s not even a consideration.

But this kind of suite isn’t really about mass appeal.

It’s something Royal Caribbean knows will get people talking. It’s headline-grabbing, it’s different, and it adds another layer to the whole “Icon Class is bigger and better” story.

And there will be people who book it.

High earners, big family groups celebrating something special, and those who just want to try something no one else has. Add in a few influencers and celebrities, and you’ve got exactly the kind of buzz this suite is designed to create.

It doesn’t need to be full every week to do its job.

Is It Actually Worth $87,500 A Week?

For most people, probably not.

But that’s not really how this level of travel works.

At this end of the market, it’s about the experience. You’re paying for something unusual, something exclusive, something that stands out from every other holiday you’ve taken.

And that’s exactly what this is.

There’s a certain appeal in being able to say you stayed here. In having that space, that privacy, and that slightly surreal feeling of being in your own three-storey “treehouse” while sailing across the Caribbean.

It’s not about value in the traditional sense. It’s about how it feels.

How It Compares To Royal Caribbean’s Other Ultimate Suites

Royal Caribbean has been pushing the boundaries of cruise accommodation for a while now, and it didn’t start with Icon Class.

The original Ultimate Family Suite on Oasis-class ships introduced the slides, bold colours and that full-on, theme park-style energy.

Then Icon Class took things further with the Ultimate Family Townhouse – bigger again, with more levels and even a private outdoor yard connecting directly to the Surfside neighbourhood.

Hero of the Seas will have that too.

The Treehouse sits alongside it (not literally!), but it takes things in a slightly different direction.

It’s still family-focused, but it feels more relaxed. Less about big visual moments, more about how the space actually works day to day.

When You Can Book It (And How Fast It’ll Sell Out)

Bookings for Hero of the Seas opened first to Crown & Anchor Society members on 1st April 2026, giving past Royal Caribbean cruisers early access. General sale followed on 2nd April.

There’s only one Ultimate Family Treehouse on the ship, which immediately makes it a bit of a talking point.

It probably won’t sell out every single sailing at this price point. But the first few cruises are a different story.

There will be plenty of loyal Royal Caribbean fans – and people with the budget for it – who want to be among the first to try it.

That “first to stay” factor is hard to resist.

So while you might see availability later on, those early sailings are likely to disappear quickly.

The One Thing People Might Not Expect

For all the talk of treehouses, games rooms and playful design, the biggest surprise is this.

It’s not really about the kids.

Yes, they’ll love it. Of course they will. But the layout, the separate spaces, and especially that rooftop terrace all point in a slightly different direction.

This has been designed to make family travel easier.

Everyone gets their own space. There’s room to spread out. And you’re not constantly negotiating who gets the sofa or the bathroom.

On a ship carrying thousands of people, that kind of breathing room is worth more than you might think.

Final Word

Will most people ever book the Ultimate Family Treehouse? No.

Will I ever get to sail it in? Probably not! Maybe after a lottery win…

Will a lot of people be curious about it? Absolutely.

And that’s what makes it interesting.

It’s not just another suite – it’s a glimpse at how far cruise ships are willing to go when it comes to creating experiences people can’t get anywhere else.

Whether you see it as over the top or completely brilliant probably comes down to one thing.

If you had the money… would you try it?
