We've done several Christmases at Disney, including last year, and we will do it again this year. Yes, it is very busy. If this was my only trip to the World ever 10 years or so, I'd probably be disappointed at not being able to do what I wanted, but since we go fairly regularly, there isn't the pressure to see and do everything, which just isn't realistic that time of year. We get our FPs, make ADRs, get there a good half hour before rope drop, and, most importantly, go with a good attitude. I'm at Disney, at Christmas, with my daughter. What's not to love?
