You might want to consider the small world nursery for the 3 year old. It is a slight extra charge, but they get so much more one-on-one attention there that I think a little who is very attached to mom would do much better there, since the nursery staff will do their best to cheer up and distract a kid who is asking for mom, whereas the oceaneers club just message you on your wave phone to come get them ASAP. Had to interrupt my spa trip and bingo game on my first cruise because of oceaneers club calls for my older children... and it turned out that while the kids asked for me at one point, they were fine by the time I got there and didn't even want to leave, grrr....
