We are going on that cruise as well! We were supposed to be on the Fantasy Jan 5-12, but had to rebook due to illness. There will be my husband's parents, my DH, my DS (3), and DD (1.5) and me. We are staying at the caribbean beach resort April 15-20 and then boarding "the big boat" as my son calls it. Can't wait!
We are sailing on Allure of the Seas from April 21-27, and then sailing on the Disney Dream for 4 days. That cruise will make my DD and me Platinum Disney cruisers!
Driving down early and visiting friends in Montgomery AL, Panama City, St. Augustine and Clearwater before getting to WDW. Gotta love having lots of friends who are snowbirds!
