When we set sail with our almost 4 and 2 yr olds(they turned 4 and 2 a couple of months after we returned), we were on deck 10 right above the Sail Away party. They loved dancing, and looking out at the water (were were on the port side), and I didn't have to worry about them getting out of sight in the busy party below. We had a great time! We will be taking them back this Sept and they'll be almost 5 and 3 LOL and I plan on doing the same thing again!
