Credit: Mattel Adventure ParkMattel Adventure Park has had a complicated relationship with opening dates since the project was first announced in 2021. The original target was 2022. Then it became 2023. Then 2024. Then, in late 2025. When the late 2025 target passed without an opening, the Mattel Adventure Park website removed any mention of an opening date entirely and replaced it with the two words that every theme park fan has learned to view with a specific kind of resigned skepticism: coming soon.
As of May 2026, a Mattel Adventure Park representative told the Arizona Republic that there is no update on the opening date for the Glendale location, which has been visible from Loop 101 with its Hot Wheels roller coasters standing over the construction site, as the months and years continued to pass.
That context matters when discussing the second Mattel Adventure Park, because it establishes a pattern. And the second location, announced in 2024 for Bonner Springs, Kansas, under the name Mattel Adventure Park Kansas City, is now facing its own set of uncertainties that have nothing to do with construction timelines and everything to do with a football team, a stadium, and a development project that has become entangled with discussions that extend well beyond themed entertainment.
The Kansas City Chiefs, currently the most culturally prominent NFL franchise in the country, are involved in ongoing stadium discussions that are directly connected to the broader Destination KCK entertainment district project, where Mattel Adventure Park Kansas City was planned. Those discussions have introduced fresh uncertainty around the Kansas City park’s future at a moment when the project had already shifted away from its original 2026 opening target without a new timeline being announced.
What Mattel Adventure Park Kansas City Was Supposed to Be
When Epic Resort Destinations and Mattel announced the Kansas City location in 2024, the vision was expansive. The park was positioned as a second destination, in line with Epic Resort Destinations’ mission to bring Mattel’s powerhouse brands to life through state-of-the-art technology and engaging experiences for the whole family. The attraction lineup was designed to mirror and, in some cases, exceed the Glendale location, which itself has been years in the making.
The planned offerings for the Kansas City park include two Hot Wheels-themed roller coasters, the Bone Shaker featuring the famous hot rod’s skull design, and the double-looping Twin Mill Racer. Thomas and Friends: World of Sodor would bring five family-friendly rides and attractions, including a dedicated indoor play space. He-Man vs. Skeletor Laser Tag would take place inside a Castle Grayskull fortress. An 18-hole mini golf experience would draw from beloved Mattel game brands, including Magic 8 Ball and Pictionary. A large-scale custom UNO climbing structure would add to the family-oriented offering.
The Barbie component was built to capitalize on the franchise’s renewed cultural momentum following the blockbuster film. Mattel Adventure Park Kansas City would feature a larger-than-life Barbie Beach House with an interactive retail experience using hologram technology, a flying theater, and The Barbie Rooftop restaurant and bar. Mattel Chief Franchise Officer Josh Silverman described the park as bringing iconic brands to life with epic roller coasters, family-friendly attractions, immersive theatre, and themed dining.
That vision has not been formally cancelled. But it has moved into a state of uncertainty that no new timeline or official statement has resolved.
The Chiefs, the Stadium, and the Complication
New reporting has connected the Mattel Adventure Park Kansas City project to ongoing stadium discussions involving both the Kansas City Chiefs and the Kansas City Royals. The entertainment district in Bonner Springs, Kansas, known as Destination KCK, has been linked to reporting on the broader negotiations around where those franchises will play in the future. When a stadium discussion of that scale enters the picture around a development project, it introduces variables that can reshape or delay component projects regardless of how far along their own planning has progressed.
The Chiefs have been at the center of the American sports and entertainment conversation for the past several years, and their stadium situation is not a quiet or isolated discussion. It is a high-stakes negotiation involving significant public funding and political dimensions that will have consequences for the Kansas City region’s development landscape, extending well beyond any single entertainment project.
Where Both Parks Stand
The Mattel Adventure Park location in Glendale, Arizona, location of Mattel Adventure Park has not opened. The website currently says “coming soon” with no date. VAI Resort, the larger development the park is part of, indicates on its website that it announces opening dates approximately nine months in advance, which, as of May 2026, suggests a potential opening no earlier than February 2027 if the timeline holds. No updated opening timeline for the Kansas City location has been announced.
Two Mattel Adventure Parks. One with no opening date after multiple delays since 2021. One is facing new uncertainty tied to an NFL stadium discussion involving one of the most famous football franchises in the country. The Hot Wheels coasters are visible from Loop 101 in Glendale. The Kansas City timeline is invisible from anywhere.
Coming soon has been covering a lot of ground for a very long time.
