We used kids nite out, I did not like fairy godmothers. The lady on the phone acted like I was bothering her by asking if the babysitter they sent over would know how to use an epi pen. After that, I canceled with them, and would never call them back.
With kids nite out, I was on the phone for 45 minutes going over my two kids ages, their sex, what they liked, what I wanted them to do while we were gone, we talked about the epi pen, etc etc. I was very much put at ease with them.
The morning of (we actually hired them to watch our two youngest for the day, while we took our two oldest to discovery cove), our babysitter showed up early, with a huge suitcase of toys. We gave her money to take the kids to the cafeteria for lunch, told her she could do anything with them at the resort (we were actually staying at the nick hotel when they came). We were gone longer than expected, and I was a wreck by the time we got back. But, no need, we walked into the hotel room to find my 1 year old happily playing with toys, and my 4 year old making playdoh cookies. She actually asked us to leave so she could play with her new friend longer.
Its been over a year since we were there, and used them, but my daughter (who is 5 now), just asked the other day when mommy and daddy were going to go away again so she could play with her super fun friend who brought her playdoh and a barbie with a pink dress to play with.
I would not hesitate to use them again, it was a wonderful service.
