I've been trying to brainstorm new lands for this area all morning, and dang it's kinda hard. It feels like there's only two options here. A.) Reroute the pathways to the Lower Lot and Studio Tour and put a big ride in the space where the Simpsons Ride and the main courtyard currently resides, and not do much else. Or B.) Keep everything as it currently is and go with a mini-land with no major rides similar to DreamWorks KidZone. The area just isn't big enough for both a major non-simulator ride and a land, and I hope we don't get another simulator.
Maybe we'll get something like Isle of Berk? Untrainable in the back where the ride currently is, retheme the current food options to be similar to the restaurants/shops at Epic Universe, and maybe if there's room add a playground?
