Going back to Launch Bay...
If they wanted to keep the Darth Vader/Chewbacca/BB-8 Meet and Greets around, but didn't want to use space such as Vacation Fun, Meet Olaf at Celebrity Spotlight and Meet Mickey and Minnie at Red Carpet Dreams, could they use the Galactic Starcruiser in a way similar to Rafiki's Planet Watch at Disney's Animal Kingdom, or Hogwarts Express at Universal Studios/Islands of Adventure? Do the insides still exist?
They could either use the buses that they were using for transport to/from the hotel, or build something to replace it, like a peoplemover/train, and take people over to the Galactic Starcruiser.
Host the meet and greets there, reopen The Crown of Corellia Dining Room (either quick service or table service with reservations) and The Sublight Lounge (could use reservations like Oga's Cantina and Space 220 Lounge if required), sell different Star Wars merchandise.
Would allow them to use what they have already built, instead of standing there empty, keep the attractions that they already have, expand the park, and remove the Launch Bay for further expansion.
