We brought three children with us on the cruise. I was disappointed with the overall experience. This is not to say we had a bad time, but it was just very trying on us:
1. Our kids are 2. 5, 4.5, and 6.5. The kids center agreed to take our youngest because she is very happy to not be in diapers. I certainly appreciated that. I did not like that if after 15 minutes your child did not want to be there, they paged you to have you pick them up. It made it impossible to get any time to relax. Normally, I wouldn't mind that but...
2. They have only 2 children pools for roughly 2500 people. Both are fairly small and were very crowded. It always required two adults to watch the kids at the pool and that was difficult with the density of children.
