Orlando is the highest on the list given that it has MGM, Universal, etc. it makes sense to keep all the different talent together, plus it makes it a hub for media/production so talent is readily available. But the most import thing is that there is plenty of building room. Orlando is also central to Miami, Tampa, Atlanta, etc. The location is by far the best.
Miami sounds great but no room. Miami is so congested where will an 80 acres studio go in the everglades.
Tampa is just trying to catch up to Miami, and it getting worried that Orlando will soon pass them up in population and downtown size. Ask Trump, Tampa is not for him. There is talks of Trump building around internationl drive, plans are early and who knows if it ever would go forth.
