In terms of the hair - I always think I have it under control, and then when I get there, I have to pull it back or change my hairstyle (and of course I just got a haircut right before the trip that I can't really pull back easily). And I have very straight hair. Expect your semi-curly hair to look nothing like what you want it to look like.
Schedule looks good to me, and I love that you have the dresses down there!
It looks like most of your days are recommended parks. I've never used the crowd calendars before this trip (and barely used them this trip), but I think following them as much as you are will be good for Squeaks.
I especially like that you have a rest day between 2 MK days - MK can be a lot, so its great to relax in between!
In my experience, BOG & CRT will be the hardest reservations to get, so once you get those, don't try to move days, but some of the others may be adjustable. We picked up both 1900PF & Tusker House (which we later dropped) within 2 months of the trip (and could have picked up Coral Reef, but I decided not to) - if you follow the ADR cancellation threads, you may be able to pick up some good stuff even if you change your days. So nothing is set in stone.
(Of course, we also got a BOG within a few weeks of the trip, but that was because they extended park hours, so we picked up a "just before the new closing" ADR)
