DHS is my favorite park and it and Magic Kingdom are the only two parks that are "must visits" for each trip. That's not to say that we don't enjoy Epcot. I absolutely love it and it is my six-year-old daughter's favorite park, but my husband hates how it has really been neglected and can easily get irritated when we are there, so it is the park we are second most likely to skip. Animal Kingdom is skipped most trips and if not skipped, certainly done the least amount.
Anyway, no, not skipping DHS. Great Movie Ride is my favorite ride in all of Disney and Tower of Terror is right up there with it. My daughter is finally going to be tall enough to ride RNRC and she is very excited about that. We all really enjoy Star Tours and can't miss that. I also can't imagine a trip where we don't eat at Sci Fi, 50's Prime Time, or Mama Melrose. We have to dine at at least one of those places if not two or even all three. And Fantasmic! Many have said that it is overrated and that's just fine with me because it means I am more likely to find a good seat in the theater when I watch it. No WDW vacation is complete without seeing Steamboat Willie steer the boat while all of the characters wave as they go by (and how cool is it that he is in black and white?). Oh and One Man's Dream! I love that. And we are fans of Disney Junior Life on Stage, as well. No way I'm skipping that park. No way.
