We also used Fairy Godmothers last trip and although I've always read great things about them on these boards, we're going to give Kids Night Out a try this time.
We have 3 kids....last year they were DS-10, DD-6, and DS-3. We had requested Vera based on advice on these boards, but she was out of town, so they sent someone else....unfortunately, I can't remember her name. Everything worked out fine....kids were safe, etc., and they said they had a nice time. She was a 'grandmother' type, maybe in her 60s, and I pretty much got the impression she spent most of her time either bribing them to be good with her little prizes or reading her magazine. Certainly no harm done, but my kids mostly told me about all of the various bargaining rules in picking 'prizes', e.g. can have 2 of this if you take 1 of that, etc. and said the sitter spent most of her time reading her magazine.
Again, the kids were safe, and that's what really counted, but I would have liked to have had someone with a little more energy or creativity to help the kids have fun.
This is a minor gripe in the grand scheme of things, and perhaps we'll have a similar experience with KNO as my understanding is most of them employ older workers (and maybe that's good).....just thought I'd share the experience.
I can say though, that DH and I had a great time at JellyRolls, and we'll definitely be doing that part again.....one evening out in the midst of 10 days of 'quality family time' is priceless even if the kids are a little bored that one night!
