Does your family not enjoy Hollywood Studios or Animal Kingdom? I see you are spending just one day at those parks. I need at least 2 days at HS to see everything.
That is a good question. Indeed, we did enjoy Hollywood Studios (and Animal Kingdom) a great bit. I would return to Hollywood Studios just for TSMM, Lights Motors Action, and Fantasmic, even if there were nothing else in the park to do.
DD14 played a big part in helping to decide how many days we would spend in each park. We loved Hollywood Studios, however I am the most adventurous as far as rides go in my family, and even I'm not really certain that I want to ride ToT or RnRC. DW, and DD14 are certain that they do NOT, and DS5 isn't big enough for RnRC yet. With those two rides out, it really isn't terribly hard to see the rest of Hollywood Studios in one day. We didn't miss much there last year, and we only spent one day. This year, we'll skip a couple of things we did last year, and we won't take a mid day break. That should give us plenty of time to see what we want to.
Animal Kingdom I am sure could take more than one day, however it was a wash out for us last year, we really didn't get much of anything done in the park, and I think that turned the kids off a bit. In addition, we live less than an hour away from the Bronx Zoo, which we go to quite regularly, so that takes some of the thrill out of AK for the kids, and neither of them is the least bit interested in EE, or Dinosaur, which again makes it a bunch easier to see most of what we want to see in one day. I don't expect that we'll get to everything in AK in that one day, but then that gives us a reason to go visit Disney World again another year.
DD14, and DS5 LOVE MK, I think it is their favorite park, and much to my surprise (and it was / is a pleasant surprise) DD14 (was 13 last year) totally got what the World Showcase is about, and fell in love with it, much the way I did when I was her age. I think the biggest disappointment for her last year was that we didn't get enough time to really explore the World Showcase. The combination of bad ADR timing, and bad weather wiped out most of our time for touring, so spending plenty of time in World Showcase was a TOP priority for DD14 this year.
