S/O Cruising - naps

MarcyIam

This may sound like a stupid question, but how does napping work for your LO on a cruise.

I saw one person mention they can provide a PNP, but do they also provide monitors that work from anywhere on the ship so you know when your LO wakes up?

I'm thinking no, so I guess you just have to either take a nap with them or check on them frequently to make sure they haven't woken up and are crying (or wandering if older) around the room?
