Disney has been around for a lot longer than that. Its about the "magic". We nerds know the issues. The tourists are just on vacation. My family has no idea that Disney is low-grade lately and hasnt added anything for 20 years, they just wanna go bc its a vacation. Therein lies my point. To US, its a standard...to them its a day away from work.
I think this is beginning to change though. I've been hearing a lot of guests begin to talk about how Disney had nothing "new" since their last visit.
Yea, guests may still go to Disney, but rather than spend their entire vacation at Disney, they're going to throw in a day or two at Universal.
