This morning I was on the phone with Kids Night Out. We are using them next week. I'll be sure to post when I get back. I think though from reading all the posts here at the Dis, both services (Fairy Godmothers and KNO) are wonderful.
We considered one of the resort Kid Clubs for our oldest and KNO for our younger boy but in the end decided not to split the boys up. We have a 7 year old and a 6 month old.
Good luck with your decisions.
