As I was changing my son's bedding early this morning because his pull-up leaked, I was wondering how this is dealt with on a Disney cruise. Can you call them in the middle of the night for new bedding? Is there any sort of waterproof mattress pad on the bed? Or do I need to look into those pads you put on the bed (like you have at the hospital)? It doesn't happen often, maybe once a month or so, but I'm concerned about it happening away from home.
