For some reason I want to say that Disney likes Modified Bit roofs.Flat roofs with EPDM (Ethylene Propylene Diene Monomer) Rubber membranes are common in nearly any climate condition, save extremely high snow loads, and even then those can be adequately accommodated with a heftier structure. Freezing temps and precipitation are not factors that would inhibit use of a flat roof. Virtually every warehouse in the world, no matter the climate, is a flat roof.
I would be surprised if they use a ballasted system (tar and gravel) though, they aren't really used much anymore on new construction. The big question is whether the EPDM will be black or white. Latest research suggests they should cover it in a white membrane.
Ballast systems are pretty much a no go in Florida due to the hazard of wind-borne debris.
