New WDI Permit Hints at Set Installation for Monsters Inc Flying Door Coaster

The Monsters Inc Flying Door coaster at Disney’s Hollywood Studios may be getting closer to its themed interior work. Walt Disney Imagineering has filed a new Notice of Commencement for set elements, and the location points right at the coaster’s construction site.

If this Monsters Inc Flying Door coaster permit is what it looks like, it marks the shift from steel and track to the scenes guests will actually ride through. Here’s what the filing says, why it matters, and where the Monstropolis timeline stands.

Quick Summary

• WDI filed a new Notice of Commencement with the scope “install set elements”
• The listed contractor is Mecca Productions, a frequent WDI vendor
• The permit address, 253 S Studio Dr, doesn’t yet exist in the district’s address database
• The closest matching address is a backstage area right next to the coaster construction site
• Set elements would be the next phase after steel, walls, and track work
• The Flying Door coaster is scheduled to open in 2028, after the first phase of Monstropolis opens in 2027

What the New Permit Says

The filing lists Mecca Productions as the contractor, with a simple scope: “install set elements.” Mecca is a frequent vendor for Walt Disney Imagineering and has worked on themed projects for Disney before.

The permit lists the address as 253 S Studio Dr. That address doesn’t exist yet in the Central Florida Tourism Oversight District address database. The closest matching address is tied to a backstage area right next to the coaster construction site.

The permit doesn’t name the attraction, so we can’t say for sure this is for the Flying Door coaster. But the location makes it the most likely candidate.

The Next Phase for the Flying Door Coaster

If this permit is for the coaster building, it would be the next big milestone in the build. So far, work on the attraction has focused on:

• The show building’s steel framework and walls
• Track supports and track installation

Set elements are where the project shifts into themed interior work. That’s when the scenes guests ride through start to take shape.

This is also the stage where a construction site starts to feel like an attraction. Steel and track tell you the ride path, but sets and theming are what make the experience.

About the Monsters Inc Flying Door Coaster

The Flying Door coaster is a Vekoma suspended coaster, and it’s Disney’s first. Instead of riding on top of the track, the ride vehicles hang beneath it.

Guests will fly through the famous door vault from Monsters, Inc., the massive system of moving doors from the film’s climactic chase scene. A suspended coaster is a great fit for that, since riders will feel like they’re flying through the vault on a door of their own.

We’ve been following the build closely, including when Cast Members signed a beam for the Flying Door coaster and the latest Monstropolis aerials of the entry gateway, fountain, and coaster track.

Monstropolis Opening Timeline

Disney has confirmed that Monstropolis will open in two phases:

• 2027: The first phase of the land, including the Glob Theater show “Welcome to Monstropolis,” Harryhausen’s, Archie’s, and the Scareporium
• 2028: The Monsters Inc Flying Door coaster

That means guests will be able to explore part of the land a year before the headline coaster opens. Imagineering has even been using VR to preview “Welcome to Monstropolis” as that first phase takes shape. A separate filing also pointed to a new Monstropolis play area.

What This Means for Your Trip

For now, there’s nothing new to see from inside the park. The coaster site is behind construction walls, and set installation happens indoors, so you won’t be able to watch it happen.

But permits like this are a good sign that work is staying on track. Interior theming takes a long time, so starting set installation well ahead of a 2028 opening gives Imagineering room for testing and adjustments.

If you’re planning a 2027 trip, expect to see the first part of Monstropolis but not the coaster. If riding the Flying Door coaster is on your list, a 2028 or later trip is the safer bet once Disney announces an opening date.

What to Watch Next

• More permits. Additional filings for lighting, audio, and effects would show interior work moving forward.
• Vehicle testing. Once track is complete, ride vehicle testing would be a major milestone.
• Opening dates. Disney hasn’t announced specific opening dates for either phase yet.

The Bottom Line

A new WDI permit lists Mecca Productions to install set elements, most likely inside the Monsters Inc Flying Door coaster at Disney’s Hollywood Studios. It suggests the project is moving from steel and track into themed interior work.

The first phase of Monstropolis opens in 2027, and the Flying Door coaster follows in 2028. We’ll keep tracking each filing and construction update as the land comes together.

I’m no stranger to Disney planning, as a Disneyland magic key holder and DVC member. I’m the person people ask for trip planning advice. But I had never been on a Disney cruise, and had heard great about Nate and decided to reach out. I’m so glad I did because we could not have been happier with our experience. His tips and insights were incredibly helpful, and he was incredibly responsive any time we had a question. Who do the Disney experts turn to when they need help? Nate, that’s who.

We’ll definitely be using him again.

Our experience working with Nate as our Disney vacation planner was exceptional. He was responsive and thorough. He gave us insights that made the trip go much more smoothly. We were able to really relax and focus on quality time as a family and have so much fun doing it! I will definitely reach out for any future trips.

Could not have wanted or expected more from Nate, our Distrips and More agent as we planned our 2025 Disney World trip. Nate was VERY responsive to emails and texts and more than willing to do whatever he could to guide us and answer our questions.  On several occasions I emailed him over the weekend not expecting a response until Monday but each time he responded before the weekend was over.  He even participated in a Zoom session with our group of five seniors as we planned our trip. He also helped us at the 11th hour when we added a family member to our travel group less than a month before our trip.  Without a doubt, I will reach out to Nate when I'm ready to plan my next trip to Disney World!

We are so thankful we used Nate to plan not only our first Disney trip, but also our second. He made the process so easy for us, especially for us since it was our first time going. There was a lot to consider and many decisions to make, such as where to stay, when to go, and what to experience. Nate really helped us narrow down what we wanted to do overall, but he didn’t stop there. He provided detailed guides to help us navigate the airport and find our transportation to the resort, as well as a guide to explore the resorts and make sure we saw the best Christmas decorations. One of the many amazing things he also did was set up our dinner reservations for us. This saved us so much stress and allowed us to get some of our top choices. From the moment we landed in Orlando to the moment we headed back home, he made sure everything went smoothly. You truly can’t go wrong with going to him for your next trip.

Nathan has been an amazing trip planner for me! So helpful and responsive. I am a very type A person -- so someone who is even more on top of their game than me -- is so so appreciated! Nathan has booked 3 trips for me (1 completed 2 pending) and it was perfection. Thanks again!

Nate has helped us with our vacation planning for the last couple of years and we couldn't be happier with his service and expertise. We've used other travel agents in the past and none of them have done as phenomenal a job to make sure every detail is taken care of as he has. Switching to Nate was one of the best decisions we've ever made. He's always quick to answer questions and works tirelessly to make sure we get everything we want from our trips. Plus, he's just a genuinely great person who is wonderful to work with. Whether you're planning a trip to Walt Disney World, Disneyland, a Disney Cruise, or any other vacation, Nate is the guy you want putting it all together! Five stars across the board!
