From what I understand, Christmas Day and Eve dinners are similar to Thanksgiving dinners- in that they are Fixed price, limited menu (Think Turkey) at alot of the resort restaurants . You can make PS 90 days out from Christmas- so yes, it's too early. I imagine that the actual menus for Christmas won't come out until after the PS have become available (and are mostly booked), so you might have to pick "blind". (It's sort of like the Candlelight processional- ressies are made LONG before the list of narrators are announced). I'll be there that week too! Jill
