OK, which would you rather visit? Mos Eisley Spaceport with the Cantina from the first movie and the rides promise? Or Generic Star Wars Spaceport with a Cantina similar to the one in the first movie and the rides promised?
First of all, Tatooine is ruled out from the start because it's a dry planet that sees no rain. Those Florida rain showers would be quite the immersion breakers. As for picking a location from the films, it's a tricky proposition, especially with endless films coming out. There is also not a single location or planet featured in every film (Tatooine comes close with 5 appearances). Harry Potter had it easier in this regard, Hogwarts is in every film, and Hogsmeade and Diagon Alley makes multiple appearances and host multiple important moments.
I was initially disappointed that we wouldn't be visiting a specific location from the films, but the more I think about the more it makes sense. They can do anything with a new planet that is a "remote trading port". The story possibilities open it up to everything from the Star Wars universe. Visitors come from all over the galaxy, so they can imagine any reason for any character having visited this location. As I said in another post, if they wanted to build a replica of the Mos Eisley Cantina, they could. The story could be the former owner of that Cantina decided to try is luck on this new planet with a cantina. Han Solo was a smuggler, maybe he frequented this planet for trading reasons. There could be a secret Rebel/Resistance base located here. They want a podracing attraction, no reason it can't be on this planet. There's also no reason a future film can't feature this place either. There are so many exciting possibilities.
