At the risk of being flamed by others...if your child loves the kids clubs as much as mine does, you could even leave your child in the very capable and concerned hands of the staff in the clubs for as long as you are comfortable doing so. (They open at 9:00 am and close at 1:00 am). Our son LOVES the club. On a prior trip, we took him to Costa Maya with us which really isn't that far away from the ship but he complained the entire way...seriously, on vacation I was hearing, "are we there yet?" "I'm hot" "I'm tired" I couldn't believe my ears! So the next day we were at Cozumel and I asked him if he would like to go to the club or with us and he wanted to go to the club! SO we let him and we went to Paradise Beach for a few hours and did a little shopping (right there at the port). By this time I'm feeling really guilty so we hurry back to the ship (thinking that he is crying and missing us) and he didn't want to leave!!! The counselor said he never even asked about us! They had fed him, made Flubber, played games, etc. He had a ball and so did we! Perfect vacation! We just returned from a 7 day on the Fantasy and my son BAWLED the night before and as we left because he was going to miss the kids club so much!
I know that a lot depends upon your child and his temperament and how his level of comfort in interacting with others but if he is the type of child that makes friends easily, the kids club might be an option for you!
