What if they would build a huge resort hotel in the former wet and wild spot with plenty of convention space. It would fit as a convention hotel neatly.
The theme will be movies (ofcourse) and guests who deside to visit the Universal theme parks will be traveling in stretched limo's with a special spot at valet parking with a red carpet like they are going to their movie premier. Transportation will be included and maybe the resort hotel could look a bit like this?
I for one wouldn't mind the short ride.
