I assume that since you posted your question on the family message board, you will be cruising on the Carnival Triumph. If so, you might be interested in some information about Carnival's youth program. I'm the new family cruise editor for CruiseMates.com and recently wrote, "Best Kids' Programs? Ask a Kid!" posted on the family cruise section. The article has a section on Camp Carnival. I cruised with my then six-year-old daughter last year on the Carnival Destiny (sister ship to Triumph) and she really enjoyed the youth program. I was very impressed with the fun family activities that Carnival has aboard all its ships too.
Hope this helps,
