Why does everyone assume the name change would focus on dropping "Studios" instead of "Hollywood"? To me, adding Hollywood to the name was the most confusing and does not fit. It's not in Hollywood and most of the IP in the park was not made in Hollywood.
The term "studios" does not have to refer to an active studio but to the celebration of making all types of media: Live action film, animation, television, music, even video games.
The park can focus on certain movie franchises (Star Wars and Pixar), several eras (Old Hollywood, Classic Rock, Golden TV), and revolving shows to promote current IP (like Pirates and Frozen)
The name has to be carefully chosen to avoid any specific IP. Disney-Lucus-Pixar Studio does not work because they could always sell off one of those divisions. It also limits the park name to movies.
The word "Adventure" would only cause move confusion with a park down the street. Adding Florida to the name does not make sense since the park is not themed to FLA.
So, if they don't want to go with simply "Disney Studios" to avoid confusion with actual studios in Cali, then my humble suggestions:
Disney Studios Experience
Disney Studio Land (might be to close to Disneyland)
Disney Exploration Studios
Disney Studios Park
