I could make this same argument about almost any IP-based land though. Avatar, Potter, whatever.
I have a friend who had a chance to go the TM previews for Hagrid. He decided not to go because he doesn't care about literally anything Potter. We've told him it's great and his response is "I don't like Potter, why should I bother with a ride I won't understand".
I've met more people like my friend out there and we certainly know they exist for Avatar, but the lands or rides within them usually will get people who have no interest in the IP to have a good time. Star Wars is really no less inviting for people that don't give a crap than those other IPs. It really just comes down to Disneyland botched the opening.
Well, usually in the summer, there IS a lot more single day and multi-day ticket sales. That's the odd thing. Tourists carry the load a lot more in the summer, typically.
