so many decisions! I think we're going to do the same thing with 2 day tickets when we go too. I was thinking about doing park hoppers this time to try to fit in one more park, but I really don't want to pay for the hoppers....sigh.
have you heard this? we've never done a party before and i'm planning on doing MNSSHP this trip. I was reading on easywdw (? I think? I've been on so many sites, I'm getting confused) and it said this....you don't need a park hopper if you're doing a party. go to whatever park that morning using your park ticket for that day. then go to magic kingdom about 4 with your party ticket. apparently, even though the party doesn't start until 7, they start letting people with party tickets in about 4. the party lasts until 1, so if you get there at 4 and stay until whenever, you can do rides and the party and didn't have to use get a park hopper to get into two parks in one day. I am confused by this. I thought you had to have park admission/ticket for the party in addition to the party ticket, but that sounds like the party ticket IS your park admission? I just want to make sure I understand this because if that's true, I won't do park hoppers this trip either.
anyway, my problem is also deciding what parks to go to. if we can only do 2, I think we'll do epcot and mk. i'd like to try to do some of the stuff we missed at epcot like see anna and elsa and do pick a pearl. of course we can't miss mk. if we can do another park the morning of the party, I would also go to Hollywood again because we missed so much there again too. I like ak, but I wouldn't be so sad to miss that one this trip.
I want to do costumes too! and I so don't blame you for wanting to do a girly one. where else can you get away with going all princessy for the night?

I haven't given it much thought yet though, but I think all your ideas are good ones. I also don't think it'd be weird if you did belle in her blue dress and charlotte was belle in her yellow dress.
and i'm not help with ADRs either--the only thing I know we're doing is hoop de doo. i'm just not much help this update, am I?!?
