I went to the 4 Disney parks just last month and gotta say I really didn't think it was worth the money.
So many things in epcot are completely outdated and I hadn't been to epcot since 2000 and I couldn't believe that 16 years later they still had some of the exact same rides and attractions in a park that is suppose to be about the future and technology.
Studios really doesn't have that much to do until all the new star wars and toy Story land stuff opens up.
Magic Kingdom just has way too many sit in a car and look at animatronics for me.
Animal Kingdom is actually my favorite of the parks due to the animals but they are opening that avatar land which really has nothing to do with the real theme of the park and is just a smart business attempt at getting people to go there.
I also went to both universal parks while I was there and enjoyed them much more then the Disney parks. My biggest complaint with universal was the overuse of 3d rides. I find it lazy and boring. The new King Kong area looks amazing so far.
All that being said I think they are all way over priced, food, parking, admission. The fact that I can get a gold season pass, gold dining pass and a photo pass for the year for around 220 for great adventure is what made me and my gf decide to get passes this year.
