Disney is going to have a lot of troubling selling those rooms because Star Wars is currently much less popular than it was twenty years ago. The new Disney Star Wars movies have been rather poorly received by fans and there is much less interest in the series from kids these days as a result. The new Star Wars themed lands at the Disney Parks have not generated the revenues that Disney predicted because of all of that.
Yeah, Disney gambled big on Star Wars land and really struck out because they didn't understand their audience well. I know for Disneyland they blacked out a lot of the annual passholders and have seen abysmal park attendance. They thought they'd get more out of town interest, but the reality is most of their ticket sales are from locals. Worse, they opened the land in June and don't expect to have 1 of the 2 rides open until early 2020. Essentially they have half the "land" wasted.
Adding a hotel on top of it, especially at that price point, will likely cost them even more revenue.
FWIW, this new resort will be in Florida, not California. The Star Wars land in Florida opens late this year, and both rides will be open in FL before CA's second ride opens.
I agree that they made some serious errors. Much of Disney parks are based on nostalgia. Disney based Galaxy's Edge on a movie they haven't even released yet. I've heard that it was originally intended to be themed after the original trilogy (Endor, Tatooine, Death Star), which I think would have been far more successful. Of course, The Last Jedi lost them a *lot* of fans, so that didn't help either.
I know I'm just one person, but the new Star Wars movies completely killed my interest in the entire franchise. And that's saying a lot because my wife and I had a wedding cake with the Millennium Falcon, Han Solo and Princess Leia action figures as cake toppers, and frosting that was designed to look like star-lines in hyperspace. After we saw "The Force Awakens" in the theater a few years ago, it just completely killed every bit of interest we had in Star Wars. It was a formulaic re-telling of Episode IV with bland, uninteresting characters played by uncharismatic actors, a script that was boring, unfunny, and took absolutely no chances, and an utter disdain for the original trilogy of movie's characters. We felt completely disrespected as fans and it was pretty clear that Disney doesn't really care about Star Wars as anything other than a way to wring money out of nostalgic fans.
We haven't seen any other Star Wars shows or movies since that one, but I hear that "The Last Jedi" was the "last straw" for a lot of other fans, because apparently it turned Star Wars into a strange postmodern sci-fi series where Joseph Campbell's theories about storytelling are no longer considered important. They lost the plot and -- as a direct result -- they lost their fans.
It probably wouldn't have been that hard to make a really successful Star Wars trilogy, especially if they had based it on the very, very successful Timothy Zahn novels from the 90s-2000s, but Disney has their agenda and whatever.
I'm not bitter about this situation, though, because there is an overwhelming number of excellent science fiction and fantasy series being produced right now and a lot of them are brand new, creator-owned stories. Fans don't really need Star Wars anymore. It's fine.
