We are scheduled to go on the 5-day Bahamian cruise in August. This is our first Disney cruise, but we often go to WDW. We will be on the cruise with our daughter, age 7, and two sons, ages 5 and 4. We go to WDW every year, which is a very "planning intensive" trip. What do I need to plan for the cruise beyond excursions? What tips can you give me to maximize our cruising experience? Thanks!
