First piece of track has been installed for the Wonder Woman ride!
Also, if you haven't tried it already, you can now do Front of the Line passes (for those of us who still have memberships) entirely on the app. It's a bit cumbersome to set up, but very easy and convenient once it is. Basically, go to the app, find the Flash Pass page. Create an account (which is just an email and password). Once done, go to the menu on that page and select "Claim entitlements". Paste your membership number (the app allows you to just copy the number if you have already embedded the pass), last name, and that's it!
Once it's set up, it basically works similar to Disney's Maxpass. You can make your ride reservations anywhere in the park--no more going to the Flashpass office for the paper passes! (Like Maxpass, you do have to be in the park... you can't reserve a ride while still at home.) It will tell you what time the ride is next available. If you like that time, you can just select it, and when the time comes, it will generate a bar code for you to scan.
Pro tips (and what makes it even better than Maxpass): Once your time window opens, there is no expiration time. You have until the park closes to use your pass. And since we still have early entry, we tried selecting our rides before the park even "officially" opened, and it let us! It will also tell you if a ride closes, and give you an option to select a different ride (small catch... as the day goes on, the return times get later and later, and high demand rides may go very quickly).
We haven't yet done a full day Flashpass with this, but after this experience, we plan to defintely use it when we visit some of the Texas Six Flags parks later this summer!
