In the early 1990s, Walt Disney Imagineering reportedly examined a large Las Vegas project that would have joined a Disney theme park with a casino resort operated by Steve Wynn. The proposal is sometimes called WestCave, a name inspired by WestCOT, Disney's planned second gate in Anaheim. Accounts describe a 320-acre site and a reported budget of $2 billion, although no primary corporate document confirms those details.
The idea made sense in its time. The Mirage, then the world's most expensive resort, opened in November 1989 at a cost of $630 million and helped move the Strip toward destination resorts. Treasure Island followed on October 27, 1993, with a pirate battle outside the entrance. Disney saw a market that was adopting themed environments, while Las Vegas saw a way to attract visitors beyond traditional gamblers. The plan still faced problems involving Disney's brand, finances, regulation and leadership.
A partnership built on separation
The proposed arrangement divided the business into two parts. Disney would supply the theme park and intellectual property. Wynn's Mirage Resorts Inc. would handle the casino, hotel operations and Las Vegas real estate. Disney could participate in the resort without directly operating a gaming business or seeking its own gaming license.
That structure addressed a long-standing conflict inside Disney. Walt Disney opposed gambling, while Las Vegas was built on it. A shared property could give adults casino gambling and nightlife while giving families Disney attractions and themed spaces. The concept also matched Michael Eisner's expansion plans. Disney had announced the $3 billion WestCOT project on May 8, 1991, and was planning more theme park growth during the period it called the Disney Decade.
Disney later described Las Vegas activity as market research. Imagineering did study locations without every study becoming a project. No signed agreement, shareholders' vote or primary document names WestCave as an official Disney project.
Five pressures arrived together
The first pressure was brand identity. Disney had spent decades presenting itself as family entertainment, while Las Vegas was built on gambling, burlesque and adult-only lounges. Disney's America in Virginia had already drawn vigorous opposition from historians and activists before its cancellation on September 28, 1994. Protesters said the park would "vulgarize history" and pollute the surrounding area. The planned project called for a $600 million investment on 3,000 acres.
Money created a second obstacle. Euro Disney opened in April 1992 with heavy debt and continued to perform below expectations. The September 1992 collapse of Europe's Exchange Rate Mechanism made visits 10% to 20% more expensive for many European tourists. Adding a reported $2 billion Las Vegas commitment while Disney was dealing with the European resort would have placed a major new demand on the company and its investors.
Regulation created a third. Nevada treats a gaming license as a revocable privilege, and the Nevada Gaming Commission and Gaming Control Board use licensing and enforcement to protect the state's gaming industry. A Disney-branded casino would have raised questions about intellectual property, operator responsibility and control of the brand. No Nevada ruling on WestCave is on record, and the licensing system offered no simple path for this unusual partnership.
Local and internal politics added two more problems. A property of this size would have competed for traffic, convention business and gambling revenue with existing resorts. Inside Disney, Frank Wells died in a helicopter crash in April 1994, and Jeffrey Katzenberg resigned as studio chairman in August before leaving the company later that year. Roy E. Disney was already dissatisfied with the company's direction. He later helped lead the Save Disney campaign, and 43% of shareholders opposed Eisner's re-election as chairman on March 3, 2004.
The influence without a credit
The Las Vegas proposal did not produce a Disney park, yet themed resort design continued to spread across the Strip. Steve Wynn told the Las Vegas Sun in October 1998 that Walt Disney had been a revelation and had exposed him to ideas he later applied to his casino resorts. The Bellagio opened that month, followed by Paris Las Vegas in 1999. Both used themed environments to make the resort itself part of the attraction. Paris Las Vegas opened on September 1, 1999, at a reported cost of $760 million, with a facade designed by architect Joel Bergman and references to the Louvre, the Paris Opera House and the Musée d'Orsay.
No public source credits Disney Imagineering with work on the Bellagio Conservatory or Paris Las Vegas. The same period produced Disney's Animal Kingdom, which opened on April 22, 1998, under the direction of Imagineer Joe Rohde after field research in Africa and Asia. Some of the company's appetite for large-scale themed environments continued there, on land Disney already controlled.
Why the park never returned
Las Vegas did test family entertainment. MGM Grand Adventures opened on roughly 33 acres next to the MGM Grand in December 1993. It closed as a theme park in 2002 and was converted to other uses. During the 1990s, resort building made the city less reliant on gamblers. By 2005, new development was moving toward adult-oriented luxury.
WestCOT was officially cancelled in 1995 due to financial restraints. Las Vegas recorded 40.8 million visitors in 2023, the highest annual total since 2019. Its major businesses remained gambling, conventions, entertainment residencies and dining. A Disney park could have added a family anchor, but it would also have forced Disney and Las Vegas to share control over a property that touched both companies' identities. Las Vegas still has no Disney park.

- October 27, 1993Treasure Island opened as Steve Wynn's next themed resort after the Mirage.
- April 1994Disney president Frank Wells died in a helicopter crash during a period of senior leadership instability.
- September 28, 1994Disney cancelled Disney's America in Virginia after financial concerns and strong opposition from historians and activists.
- 1995WestCOT was officially cancelled as Disney reduced or reconsidered several major expansion plans.
What the video leaves out
The research records that the Mirage was the world's most expensive resort when it opened. It also gives more precise figures for Disney's America: a planned $600 million investment on 3,000 acres. Those details help show the scale of Disney's 1990s expansion plans, although they do not confirm a Las Vegas agreement.
Paris Las Vegas opened on September 1, 1999, at a reported cost of $760 million, and architect Joel Bergman designed its themed facade with references to the Louvre, the Paris Opera House and the Musée d'Orsay. Research found no public credit connecting Disney Imagineering to that design or to the Bellagio Conservatory.
