My daughter and I just went on a last minute, 4-night cruise this past month. We were able to take advantage of a Florida resident discount this time. Now we are looking to take a 3 or 4 night cruise at the beginning of December. If you book in advance and a discount becomes available, does anyone know if Disney will refund any differences? We kinda need to plan this coming trip in advance, so if we must pay the higher price we will.
