I can understand fans of the original Epcot and seeing it's more or less destruction, reaching their tipping point. I didn't really go to Epcot as a kid, I don't have the fond memories like I do of past MK attractions, or parts of the original MGM. Maybe I'd have a different attitude if I did. I wasn't an adult during the heyday, for the 70s and early 80s I wasn't even alive, so had I lived it I can understand where many are coming from, and I do understand. Personally I'd love nothing more than to turn back time and have Energy pre-Ellen, World of Motion, Horizons and original Journey into Imagination back. The damage to Epcot started a long time ago, unfortunately.
And honestly, I don't find the parks to be that unkempt like many do. The monorails need work. The bathrooms aren't the best. I've noticed a decline in customer service (I see so many more miserable castmembers than I ever remember seeing), but none of those are tipping points for me yet.
I'm actually staying on-site at Universal this week, Cabana Bay, for their passholder night on Thursday. I think they do treat their passholders better. I think they have stepped up their customer service but I can't say I've been wowed by them, but everyone's mileage may vary on these like these.
I have to say if I had to pay for a week on-site at either Disney or Universal for more than one person I'd look elsewhere for a vacation.
