How does the kids program work on port days? We are thinking of doing an excursion in Belize, but the excursion is 8 hours--far too long for our 4 year old. I cannot find any information regarding the hours of the kid's program on port days. Can we hire a babysitter to watch him so he will have fun too? How do other parents handle this? We had planned to have the kids with us most of time, but really want to try snorkeling.
