What Could’ve Been: Disney’s Most Ambitious Park Expansions That Never Happened
Disney loves to think big. But sometimes, those big ideas get cut — hard. Whether it’s due to bad timing, busted budgets, or opening flops, some of the most jaw-dropping plans for Disneyland Paris and Tokyo Disney Resort never even made it past the blueprint stage.

If you’ve ever walked through Fantasyland and thought, “Wasn’t there supposed to be more?” — you’re not wrong. From underwater dining to glacial thrill rides to entire lands that disappeared without a trace, here’s a look at the ambitious international Disney projects that were canceled before fans even knew what they were missing.
Let’s start with Disneyland Paris, aka the crown jewel that almost collapsed.
When the Paris park (originally EuroDisney) opened in 1992, it was a visual masterpiece — and a financial trainwreck. French critics called it everything from “cultural imperialism” to a “cultural Chernobyl,” and with fewer-than-expected guests, Disney scrambled to cut costs. Hotel wings were shuttered. Staff were laid off. And most of the bold second-phase plans were unceremoniously axed.
One of the biggest casualties? Discovery Mountain. Not to be confused with Space Mountain, this was something much more massive. Picture a steampunk mountain housing not just a roller coaster, but also a full walk-through Nautilus submarine, a Horizons-style dark ride straight from EPCOT, a train station inside the mountain, and even a vertical free-fall tower themed to Journey to the Center of the Earth. Only Space Mountain survived — a great ride, yes, but a shadow of what the original mega-mountain was meant to be.
Another killer concept that got washed away? Lava Lagoon. This Polynesian-style water park was going to be tucked behind Sequoia Lodge and Newport Bay Club and would’ve blended indoor and outdoor thrills. The indoor section was set to feature a massive volcano packed with slides, a wave pool, a lazy river, and themed raft rides — while the seasonal outdoor section would’ve brought sandy beaches and more splash zones. The project drowned in red ink before ground was ever broken.
And yes, Disneyland Paris was supposed to get its own version of Splash Mountain. Land was carved out for it in Frontierland. It was a done deal — until the budget caved in. It’s ironic, because decades later, the resort is finally getting a similar ride system in a new Lion King attraction under construction at Walt Disney Studios Park (which is getting a full rebrand as Disney Adventure World). Talk about a long wait.
Now let’s jet over to Tokyo, where things are a little different. Tokyo Disney Resort isn’t owned by Disney — it’s run by the Oriental Land Company (OLC), who license the brand and hire Imagineering to do the design work. That means OLC calls the financial shots, and when they pivot, dreams get parked.
Back in the late ’90s, Imagineers cooked up a re-theme for Tokyo Disneyland’s Tomorrowland that would’ve blown minds. It was called Sci-Fi City, and it took cues from retro-future aesthetics — think anime meets The Jetsons. The land would’ve featured a new version of Space Mountain with added show scenes and a custom soundtrack, plus original rides like Rocket Bikes, Lunar Racers, and a walk-through Sci-Fi Zoo packed with animatronic aliens. But before it could take off, OLC shifted all their resources toward building Tokyo DisneySea, and Sci-Fi City was dead in the water.
Another big Tokyo idea that went nowhere was Mickeyville. Long before Toontown became the standard, Mickeyville was in early development with a medieval storybook twist. Inspired by Mickey’s old-school shorts like The Brave Little Tailor, the land would’ve had a boat ride from Donald’s dock, candy shops themed to Minnie, and a huge live show theater. Eventually, the more familiar cartoon-style Toontown took its place.
And then there’s Glacier Bay — possibly the most bizarre (and most fun-sounding) land to never get built. It was considered both for Tokyo DisneySea and Hong Kong Disneyland at different points. The pitch? An icy adventure zone with jet-ski rides on a frozen lake, sledding hills, interactive arctic science stations, and a wild indoor coaster that took guests deep inside Glacier Peak. It was like Disney’s answer to an indoor ski resort, but it never made it past the design phase.
Lastly, we have the tale of the Frozen land that almost was. In 2015, Tokyo DisneySea announced a new Scandinavian port that would fully bring Arendelle to life — castle, fjords, and all. But the plan was quickly shelved in favor of a Fantasyland expansion at Tokyo Disneyland. Some of the concept did eventually make it to the brand-new Fantasy Springs area, which opened in 2024, but the full standalone port never materialized.
In the end, these scrapped ideas remind us that behind every castle and churro stand, there’s a world of what-ifs. Some projects might get a second chance. Others are just lost magic. But it’s clear Disney has never lacked imagination — only the budget to build all of it.
