Thanks everyone!
We plan to go to AK on an early entry morning day and ride Everest before the park opens to general admission. My son and daughter-in-law want to do the safari ride earlier in the morning, so we got a FP+ for that at 9 AM. I think we'll then go to the 10 AM Lion King show standby while we're in that end of the park, and before using the our other FP+s scheduled for 11 AM (Dinosaur) and noon (raft ride for 2 and Everest repeat for 2 "who shall remain dry"). We'll do standby for Tough To Be a Bug, and walk the animal trails and take the train to what used to be called Conservation Station at a leisurely pace. We'll probably finish up with the 3 PM Finding Nemo show. We plan to end the day strolling through Epcot's Food & Wine Festival for dinner.
We've been to Disney World well over 30 times over the past 30 years, but this is the first trip where we had to be so scheduled so far out from our trip. I hope the new system will be worth the loss of spontaneity.
