We travel with friends who have young children and they have used Kids Night Out and loved it. In planning our next trip together, they asked to make sure to book with Kids Night Out again for a grownup night out! I have read that if you need to use the multiple days during your trip you can often request the same person. (YMMV)
I also saw a “mothers helper” type option for those that may benefit from an extra set of hands and eyes IN the parks. You do have to buy the helper park admission, in addition to paying their rate. No experience with this but a nice option for some people maybe.
