This post is from last year when we were going on Disney. We ended up on a land and sea trip with the Wonder being our ship. Luckily I got my daughter daytime potty trained before our trip, but she is still tiny and did not look old enough to be potty trained. No one questioned whether she was or wasn't. There were also alot of little ones in the pool with their parents. The signs are posted but no one said a thing. Good luck to all. I know this a touchy subject for all. The cruise lines, if they enforce this rule are just going by a federal safety guideline.
