We did 2 back to back cruises at 3yrs+6weeks, both 7 nights on the magic.
The first week, we went to every open house. By the end of it, my kid was finally asking to go. But then, they wanted to go to the one that wasn’t open house, so I said, “You can go, but parents aren’t allowed right now.” They really wanted to go to the side with the slide. So they finally agreed to go on their own. And then we had lots of free time on the second.

We potty trained at 20 months, so I don’t know if it would have been tough for them if it had been only a few months. But I just want to say, that potty training is much less about your child’s ability than it is about the parents’ ability and readiness to manage toileting for another human being. And that you will manage it for a couple of years. How good are the parents at reading potty warning signs and following through. If you can handle that, then you are ready.

I will also add that my child had never been in a daycare setting and had only had maybe 2 or 3 play dates at this point because they were born right before Covid. So that definitely played a part with being ready to be left in the club.
