I think you need to go by what
DCL says and not the DIS boards. I am not saying that the boards are not correct but when you board and explain to DCL that this is what you were expecting bc that is what their website states then I think you should be fine.
Last cruise DD was brand new potty trained. I read up and down the boards how they can't have any accidents, they don't offer any help, if your kid has an accident they are out of the club for 24 hours. When getting to the port and speaking to the clubs manager, it was NOTHING like that. They marked Maddys file that she need reminders. They were great about it and we never had one problem.
So I stressed for months about something that was not even an issue!
