Hi Roberta,
There are a few options. You can use the Kids Night Out Service. It is a child care service that will come to your room or you can have someone with you if you need help in the parks. Here is there phone number
1-407-828-0920. They charge an hourly rate and all of the sitters are CPR/First Aid certified.
Another option if you are staying at one of the Walt Disney World Resorts is using one of the
children's activity centers. It is for children age 4-12 who are potty trained. The centers are open from 430pm - midnight. The kids get to have dinner there, play games, activities, etc.
Here is more information on where the centers are located.
Depending on what your plans are, either one of these options is sure to help!
If you have any other questions, please let me know.
Carrie
