I did a lot of research on it because we were planning to go to Disney in September with friends and we were going to get sitters for the kids while we went to dinner one night, but now my husband will be gone for that month so we had to reschedule the trip and now we don't have a reason to use a sitter. But anyway, I couldn't find much information. I read a bunch of reviews and they were all positive, said the sitters came with tons of toys and activities and the kids had a good time. I have never left my kids with a sitter before so I don't know how they would handle it. I was thinking of letting me 3 year old go to the Neverland club for a few hours in December just for fun (he'll be 4 by then)...I guess it depends on how he is around strangers at that point.
Also I think on top of the hourly rate you have to pay a travel fee too.
