Change has been a constant at Disney World since the very beginning, with countless rides and attractions coming and going over the last 5+ decades. However, it can feel like that for every change that has actually been made, one has been announced, hyped, and promoted by Disney before disappearing into the blue sky aether and never spoken of again.

From rides and pavilions to lands and even a FULL hotel, all of these projects were announced — and some even had construction start — before they were quietly abandoned.
Western River Expedition
During early development of the Magic Kingdom, Imagineering legend Marc Davis — of Haunted Mansion and Pirates of the Caribbean fame — planned his magnum opus for the park: The Western River Expedition.
This massive E-Ticket boat ride was planned to be housed in a gigantic show building known as Thunder Mesa that would have towered over the park’s Frontierland. It was meant to be topped by a mountain range and a mine train roller coaster attraction on its exterior. The main feature would have been a boat ride that would feature hundreds of cowboys, Native Americans, and animals telling the story of the American West in Davis’s style of comedic vignettes.

While Thunder Mesa was initially planned as an opening day attraction, it was moved to the second phase of Disney World’s construction due to budget issues and was scheduled to open 3-4 years after opening day. That didn’t stop Disney from advertising the ride, as the Western River Expedition was included in promotional materials about the park, and a preview center of upcoming attractions.
However, after guests’ complaints about the absence of Pirates of the Caribbean — which executives had decided not to include in the Magic Kingdom due to the idea that pirates were “overexposed” in Florida — the budget for the attraction was shifted to building a shortened version of Pirates of the Caribbean. The land set aside for Western River Expedition is now home to Tiana’s Bayou Adventure and Big Thunder Mountain Railroad, which came from the mine train that would have been part of Thunder Mesa.

Beastly Kingdom
During the early design stages of Disney’s Animal Kingdom, a land based on mythological animals that would have been split into sections based on good and evil was planned to be one of the park’s anchors, to the point where there was a dragon in the logo. The “good” half of the land would have been built around a walkthrough attraction known as The Quest of the Unicorn, as well as a boat ride attraction titled Fantasia Gardens.
Meanwhile, the “evil” side was to have been the burnt-out remains of a medieval village, the skyline of which was to be dominated by a larger-than-life castle. The castle would have held the land’s, and arguably the park’s, premier attraction: Dragon’s Tower. The thrill attraction would have used an inverted roller coaster ride system to tell the tale of a group of bats stealing treasure from the evil dragon who lords over the castle and village.

The land was pushed to the park’s second phase due to budget overruns – allegedly, DinoLand was chosen over Beastly Kingdom due to potential toy sales. Before Disney could begin work on the land, Universal opened Islands of Adventure in 1999.
The new park featured Lost Continent, a land based on mythological creatures that bore many similarities to Beastly Kingdom… and perhaps not coincidentally was designed by former Imagineers who had been laid off when the Animal Kingdom land was pushed back.

Pop Century Legendary Years
The resort known as Pop Century — a Value Tier resort that celebrates the pop culture of the second half of the 20th century, featuring areas set to the 1950s, ’60s, ’70s, ‘80s, and ’90s — was originally supposed to be double the size. Originally, the Legendary Years section of the resort was set to be built across from the “Classic Years” ’50s-‘90s section, themed to the first 50 years of the century.

Construction had already begun on the resort when the September 11th attacks cratered the tourism industry. Disney paused work on the hotel, and left it paused and unfinished for YEARS. In the early 2010s, the site was refurbished and completed into the Art of Animation Resort.

Mary Poppins Attraction
Our next three entries all revolve around the “reimagining” of EPCOT, which took place in the late 2010s and early 2020s. The first is the Mary Poppins attraction that was planned for the World Showcase U.K. Pavilion. At the 2019 D23 Expo, Disney had Dick Van Dyke himself announce the attraction (later revealed to be an indoor teacup-style attraction). However, following the pandemic, the ride was cut for budget reasons.

Play! Pavilion
Another planned EPCOT “reimagining” project that fell victim to the pandemic, the Play! Pavilion was announced to be built in the former Wonders of Life Pavilion.
Planned attractions for Play! were announced to include an Animation Academy-like experience where Edna Mode teaches guests to draw, the Hotel Heist interactive game hosted by Zootopia’s Judy Hopps and Nick Wilde, an arcade, a Monorail Mark X, and a water balloon fight video game experience with various Disney characters.

Like many Disney projects at the time, the 2020 COVID pandemic massively curtailed Disney’s plans for the Play! Pavilion. In March of 2020, the parks closed, and construction halted.
Even after the Disney World parks reopened later that summer — and work on other EPCOT projects resumed — work on the Play! Pavilion remained stalled, and Disney remained quiet on the subject. In 2023, the pavilion was quietly removed from park maps, and the following year, Disney said the opening of Communicore Hall marked the end of the “reimagining” project

Spaceship Earth 2019 Refurbishment
Even EPCOT’s icon wasn’t spared from the pandemic’s effect on ongoing projects. A major refurbishment for the ride was announced as part of the project, and was supposed to feature “new scenes reflecting the universal nature of the human experience.

A new guide and all-new narration will focus on the storytelling that brings people together.” However, the project was paused with the onset of the COVID-19 pandemic and was not continued. A smaller, infrastructure-driven refurbishment was done in 2020.

Fixing the Yeti
Ah, the Yeti at Expedition Everest. At the time of the ride’s opening in 2006, this massive animatronic was hailed as the largest and most advanced Disney had ever built. The massive free-moving animatronic Yeti in the center of the “Forbidden Mountain” was one of the ride’s main promotional points. However, within months, the Yeti was stuck in B-Mode, unmoving with strobe lights pulsating to give the illusion of movement (hence the nom de plume “Disco Yeti”).

This was allegedly due to structural damage the powerful animatronic was doing to the mountain when fully operational over the years. Disney officials – including Joe Rohde himself – have claimed fixes to the Yeti were coming, as of 2026, none have arrived. Every time we pass under “Disco” Yeti, we’re simultaneously reminded of what we’re missing out on.

All of these canceled changes provide a view into an alternate universe Walt Disney World that COULD have developed over the past few decades. Stay tuned to AllEars for more on the Disney World that might have been.
