Just playing around with "what if" concept. Probably not entirely the best solution, but I was bored.
Light green: new flat open space (demolished Panda and Universal Experience)
Dark green: two bridges/ramps to and from the new attraction.
Light Orange: previous backstage building, now new gift shop and bathroom with entrance from attraction bridge exit.
Dark orange: existing bathrooms
Dark blue: existing character shop/old Mummy souvenir store
Light blue: new attraction.
I added bridges/ramps to the attraction to provide clearance bellow for the fire exits or whatever clearance apparently needs to be there.
I'm very curious what they'll eventually do.
