We've been on 3 other Disney Cruises (2 of them this same Spring Break week) and all 3 times the ship's been sold out. The busiest places on the ship are the pool areas, especially on sea days. We always pick one port to just stay on board and enjoy the less crowded ship. Getting seats for shows can also be tricky on a full ship. Get to the theater at least 30 min. before the shows start.
Since we've done this itinerary before, we really don't have any big excursions planned (we did the dolphin swim at Grand Cayman last time.) Thinking of renting jet skis in Key West. Planning on walking around, shopping in Cozumel. We didn't get off the ship there in '09 because ours was the first
DCL cruise allowed to dock after Mexico was on lockdown for weeks from H1N1. Needless to say, we were a little hesitant to step foot in Mexico, especially with the kids.
I've got all our clothes ready to go. I purposely dress my two boys alike each night for dinner just to make things easier (i.e. in matching polos.) Don't laugh at me, but I make a chart of what each of us is wearing every night for two reasons: 1. So we somewhat coordinate (i.e. don't clash in pictures) and 2. So we don't have to think "What are we wearing tonight?" It just helps ease my "Mommy" stress having all that planned out beforehand. Even my husband thinks it's great to just look at the chart and say, "Okay, I'm wearing this tonight!"
The entire ship is sold out! That makes me freak out just a bit. Now I'm really worried about being able to get a cabana on Castaway.
I was starting to get worried.
