Phoenix has more large-scale development happening at once than most people realize, stadiums, tech campuses, mixed-use districts, more than any one person can track. Each week we're picking one worth watching and giving you the real version, not the press release version. This week: VAI Resort and Mattel Adventure Park in Glendale.
I've been keeping an eye on this specific project for over two years now, ever since it broke ground near State Farm Stadium. The completion timeline has been pushed back so many times at this point that I've started wondering whether this is normal construction-and-permitting delay, or whether there's a bigger issue with the developer that's actually driving it. So I went back and dug into it again to see what's actually changed since the last time I looked.
The part most coverage is missing
Turns out something real did change, and it's the kind of thing that answers my own question. On August 21, VAI Resort confirmed something that had apparently already happened without anyone announcing it: the company is now the developer, owner, and operator of the Mattel Adventure Park itself, not just the resort built around it. Glen Bilbo, the man who'd led the theme park piece of this project since it started, has stepped away. VAI won't say when.
What's actually confirmed
VAI Resort broke ground in 2021 under the name Crystal Lagoons Island Resort, aiming to be finished before Glendale hosted the 2023 Super Bowl. That deadline came and went. Since then the project has grown considerably in scope and cost: from roughly $350 million to somewhere around $1.2 to $1.3 billion, from 600 hotel rooms to 1,100, with an 11,000-seat amphitheater and a theater added along the way. The Fisher family, of civil construction firm Fisher Industries, took over the resort side in 2022 after the original financing fell through, and are largely self-funding it now.
The opening date has moved every time it's been announced. Late 2023, then late 2025, then sometime in 2026. As of last fall, VAI officials stopped giving a specific date at all, saying they'll announce one roughly 9 to 12 months before it actually happens. By this spring, another informal target had quietly come and gone too, so even the loose 2026 window looks doubtful now. That means, as of today, there's no real public timeline for when either the resort or the Mattel park opens.
There's also legal and political noise around the project worth knowing about. A May 2025 special election over rezoning tied to parking and office space came back split, some approvals held, others got struck down, adding fresh uncertainty to the schedule. The stadium authority that owns State Farm Stadium separately sued the city of Glendale over parking, a case that's still open. VAI Resort is also suing a contractor it accuses of falsely claiming a piece of ownership, and that contractor has countersued. A 22-year-old subcontractor employee died in a fall on the site in late 2024, and state safety regulators proposed a $27,423 fine against the subcontractor. None of that has stopped construction, but it's part of the real picture, not just the renderings.
So what's actually been built after five years? Some real progress: the main hotel tower structure is up and anchors the north end of the site, the conference center along Loop 101 has reached three stories, the amphitheater has its screens, video boards, and stage effects installed, and a separate office building on 95th Avenue is close enough to done that VAI has floated a 6 to 8 week move-in window. What hasn't happened: no hotel rooms, restaurants, or the amphitheater are open to the public, and there's been no public construction update on the Mattel Adventure Park itself since spring. Five years after groundbreaking, the site has real structures rising on it, but nothing here is finished and operating yet.
Glendale's own city manager remains publicly confident it will eventually get built, calling it a transformational project for the city and the West Valley. Construction has continued through all of the above. Whether "eventually" means next year or several years from now isn't something anyone outside the project can currently answer.
Where this actually sits
VAI Resort and the future Mattel Adventure Park are on roughly 60 acres at the southeast corner of Cardinals Way and Loop 101, directly across from State Farm Stadium and inside the Westgate Entertainment District. It's about 25 minutes from Sky Harbor.
The immediate area around it, La Buena Vida and Rovey Farm Estates, is already built out and has been shaped for years by Westgate and the stadium being there, regardless of whether this specific project ever opens. A bit further northwest, Arrowhead Ranch and Arrowhead Lakes are established, higher-end Glendale neighborhoods that aren't dependent on VAI at all.
Should this factor into a neighborhood home search
Honestly, not as a near-term catalyst. A project that can't get its own developer to give a firm opening date isn't something to price into a purchase decision right now. If you're looking in the Westgate area for the stadium, the entertainment district, and the West Valley location that already exists today, that's a real reason to buy there. If you're looking specifically because you're expecting a finished Mattel theme park to show up and move the needle on values, you could be waiting a long time, and nobody involved in the project itself can currently tell you how long.
The overlooked variable here isn't whether VAI Resort is capable of getting built. There's visible, structural progress on the site, that part is real. It's that the project has changed hands, expanded scope, and pushed its own opening estimates so many times that nobody, including the people running it, can currently tell you when "built" turns into "open." Treat it as a long-term amenity that's genuinely under construction, not one you can put a date on.
