Thanks for the replies so far, I can manage expectations but it's the not being able to walk around like a normal person is what's hard to think about. Plus the other times we've gone we've never had to bother with Early Entry etc., we've had enough days to do what we want and be lazy and slow. The crowds, having to get up super early (for us), possible cranky husband to boot. It's making me worry. Funny, before I was worried about weather, now I am more worried about crowds.
If it weren't for all that stuff closing next year, I probably would just cancel the trip. We've never been at xmas time (always wanted to), never seen F! (always wanted to) and even reserved a BB F! reservation for this trip. I will gladly eat $200 cancel fee to keep husband less cranky though. I thought going during the 60th would be a neat bonus. ha!
Please keep posting if you have any experience and I will keep talking to my family. See if they would still be into it if it were very busy, and I will keep reading about how it actually is to be there when it's that busy. Pragmatic advice, etc.
