Star Wars is the only fandom I know of that has a sizable contingent of "fans" that hates everything about the thing they're fans of. All that's really happened here is they redirected their rage at George Lucas over the Prequels and Special Editions into rage about Disney and diversity.
At any rate, if you made a Venn diagram of LARPers, Star Wars fans that actually like Star Wars, and "people who can afford to stay at this hotel", the overlap in the center is more than large enough to keep the hotel sufficiently booked for years. Especially if they manage to deliver on enough of their hype that they get repeat guests.
