Depending on the time of year, A & E and 7DMT will not likely be available 30 days out. We didn't even try for those (all 10 are adults...youngest 26...so we aren't real big on character meet and greets). We plan on doing the 7DMT on Tuesday 16 Dec during the
MVMCP. Here's what we did get 30 days out:
MK: Space Mt, Splash Mt, Thunder Mt
AK: Dinosaur, Expedition Everest, Kilimanjari Safari
EPCOT: Soarin', Spaceship Earth, Journey into Imagination
HS: ToT, RnRC, Muppets 3D
The way it worked out, we didn't need to change any of our ADRs, we will see all the major shows once (Illuminations, Fantasmic, Beauty & the Beast, etc...), we are doing MVMCP and Hoop-Dee-Doo Revue.
It took some pre-planning/scheduling decisions ahead of time, but it all fit together nicely. With a smaller party, I imagine it will be even easier with a little thought before getting started.
Good Luck!!
