I've used Kids Nite Out twice, once when DD was 15 months and again at 24 months, and I can't recommend them enough. Both sitters came 20 minutes before their scheduled time to over schedules (if you have one), concerns (if you have any), and to be introduced to my daughter without me rushing out the door (not that I'd do that to begin with). They won't do any activities involving water (a huge plus), and they spent the majority of the night at the playground and walking around the resort grounds. Both times I returned at 11:30p and DD was fast asleep, lights were out and the sitters were studying/reading at the table with a booklight.
