We are on the Dec. 6 Wonder. Our plan is to compare the price in Dec. to the release date price. If it is a better deal to rebook on-board with the OBC and 10% discount, we will rebook the reservation and apply our deposit. I don't think it will sell too much before December...especially because everyone wants to go to Alaska. That and it is still sooooo far away!!!
My friend and I are on the Dec. 6 Wonder, too!
