I could see some advantages to having the 4th gate be something like a Warner Bros. Movie Park.
1. A plethora of popular IP such as DC Comics, Looney Tunes, Scooby-Doo, Tom & Jerry, The Flintstones, LotR/Hobbit, Blade Runner, The Matrix, Mad Max, Mortal Kombat, Austin Powers, Gremlins etc.
2. It could be where the resort keeps it's BIG coasters.
3. More resources to move faster.
4. Recoup some investment costs through real estate lease, percentage of merchandise sales, etc.
