Anyone had experience using baby monitors on board? Our daughter has pretty fixed sleep patterns, and she'll be asleep fairly early. I don't much care for the idea of leaving her at the kids club to fall asleep in front of a movie, which seems to be the only other option (besides sitting in the cabin in the dark). I thought if a baby monitor would work on board and if we get a cabin near the restaurants (our monitor has a 500 yard range) we could tuck her in and have dinner or sit in a nearby lounge. I don't know if this is practical. Any tips would be helpful.
