I used in room babysitting services at the Grand Californian last year. The service was professional and I was able to interview the babysitter by phone beforehand. I was a bit nervous about it, but the kids ended up really liking the sitter -- she was younger (under 20, I'd guess) and the kids immediately took to her. They mostly just watched movies in the room and I had the sitter call me every half an hour - just to be sure things were ok. We were out for probably 3 hours and the sitter managed to get my 1 1/2 and 3 year old to sleep. I was a little nervous, but my experience was good. And it was so nice to have an evening alone without the kids.
