I'm not sure what you mean, my whole point is they won't , and that's an unfortunate side effect of IP. All certain people need to hear is it's Marvel and a whole segment of people will lose interest . Even if the rides are amazing, they'll be turned off. All I'm saying is it's more limiting and alienating than something more general and non IP specific. If I say, "hey Disney just opened a new land with three awesome rides. A roller coaster, a drop ride, etc." That would probably be interesting to anyone with any care to ever visit a Disney theme park. But if I say "Hey Disney is opening a Marvel land with a Marvel drop ride, a Marvel roller coaster, and etc." I'll have lost the interest of a certain segment of the original group because all they hear is Marvel and know they don't care.
Yes, it will attract a certain segment too, but I have a feeling that most of the people it will attract would have been interested in visiting any new thing at Disney.
