My dd had just turned 6 when she went on her first
DCL cruise. It was the perfect age to take her because she was absolutely in love with all the princesses and Mickey and friends. The first night of the cruise we were walking down a hall and ran into Rapunzel. She sat down and talked with my dd for a long time, I kept telling dd that we should let Rapunzel go, but Rapunzel said it was OK, and she just kept talking to dd. After we left Rapunzel, we ran into Tiana and she did the same thing, sat and talked with dd for a long time. They really were the perfect princesses, you could tell they both really loved children. My dd loved the club at that age and would happily go to them for a few hours each day. I must admit though, I don't feel like I really took advantage of the adult areas/activities. I feel like I spent too much time just making sure we went to every character greeting and activities that my dd would like and didn't do much of anything else. My dd is now 9 yrs old and doesn't really care about the character greetings, she is over the whole princess thing. I had to drag her to get a pic of us with Donald and Pluto on our last cruise. I have to say, it's nice being able to skip all the greetings, gives us a lot more time to enjoy other things. I'm glad we did them when she was younger and still cared about the characters. Now if they had the characters from the Descendants movies on board I would have to pry her from them. I know my dd wouldn't have gone to the club when she was 3 or 4 yrs old, now she loves going to it. On our last cruise we went to get her so we could eat lunch together and she didn't want to leave. Another mom with a little girl about 3 or 4 yrs old was begging her dd to go into the club. I felt bad for her, she said her dh and her hadn't had a second to themselves because her dd refused to go to the club. Not sure how old your kids are. If they are toddlers, they won't be able to go into the pools(unless they are completely potty trained), but there are separate splash areas on the ships for toddlers-3 yr olds. My dd never went to the nursery, but I've read good things about it also on here.
