I think your son, regardless of his age will have a blast. Our son is three and he's going on his third cruise in October. He was 18 months & 2 1/2 on the other two and he had a blast. We went on the Dream without him in February and truly missed him but still had a good time. We are doing the Dream again because of the splash zone that the other ships we've been on didn't have. I hope you enjoy your "family" vacation. Have the time of your life!
