Change #1 - Early Morning at Animal Kingdom is OUT
This may seem strange - Animal Kingdom opens an hour earlier than the other parks, so it only seems to make sense to visit it first, even if for just a few attractions. In fact, my initial plan was to experience two attractions at Animal Kingdom (Expedition Everest and Primeval Whirl)
However, under further review, I have decided this is simply a bad idea. Here's why:
Even if I'm the first person in the park, and on the first ride of Expedition Everest, I probably won't be done with that attraction by 8:10. Add in Primeval Whirl, and it's 8:20. Run back to the car and drive to Hollywood Studios, and I get there at 8:45-8:50.
Here's the problem - Hollywood Studios often opens 10-15 minutes early, as early as 8:45. If I arrive right at opening, and several people are in line at the turnstiles ahead of me, I will not be on the first Toy Story Mania ride - it's going to cost me an extra 10 minutes or more. That ten minute delay will mean delays for the other attractions at Hollywood Studios. Ultimately, it could cost me 30 minutes or more at Hollywood Studios. And that means arriving at Epcot 30 minutes later, leading to longer waits at Epcot as well. This could lead to an hour delay or longer!
Instead, I will plan to visit Expedition Everest in the late afternoon with the rest of Animal Kingdom. Expedition Everest has a "single rider line" so I can get through it with minimal delay around 3:00.
Change #2 - Ariel's Undersea Adventure is (likely) out
As has been reported many places, the Fantasyland Expansion has been open off-and-on for the last week. so I added Ariel's Undersea Adventure. But since that point I've learned that it is unlikely that the Fantasyland Expansion will be open when I'm there (unfortunately). So I'm going to add a new attraction to the list to get back up to 25. I'm debating the Jungle Cruise, Peoplemover, or Barnstormer.
