Given that you were able to get a reservation for 12/11, I just called back to see if I could get one, since I'll be at WDW at the same time as you. I was told that now they're only taking phone reservations for 7 days out because as of tomorrow, reservations will be available on
MDE. I questioned this, saying that I called on Saturday and was told they were booking 25 days out, and she just repeated that as of tomorrow they'll be on MDE.

Growing pains I guess...and I guess I'm getting up at the crack of dawn tomorrow to try to get a reservation!
