Need some groupie advice. I'm counting the days until I can make my reservation for next Dec.

We're giving serious consideration to going over Christmas next year rather than early Dec. It will be on a Sun. next year so we're considering arriving on the Wed. or Thu. before & leaving on Tue. We may need a 2 BR instead of our normal 1 BR because I've invited my mom to join us. She still has not given me a definitive answer, but she's going to have to soon whether she likes it or not!

I understand 2 BRs are one of the hardest to book & given that's it's actually over Christmas I would imagine even harder. So am I going to have to walk this reservation? I hate the idea of doing that, but I don't want to lose out on a room either. What do you all think? And am I crazy to be considering going over Christmas rather than early Dec.? Obviously the crowds would be much better early in the month, but it would also mean the kids missing more school. Any thoughts would be appreciated!
