Hello, Maira!
I hope you were able to secure a registration to your desired race during the 2016 Disney Princess Half Marathon! All races during this royal weekend have currently sold-out.
If you are all set and ready to run with your Prince Charming, I recommend utilizing the services of
Kid's Nite Out. This is an independent, Disney-endorsed company that provides in-room certified childcare available 24 hours a day, seven days a week. As Disney itself does not offer a childcare service that would be available during the hours you are running, going through
Kid's Nite Out is your best option.
You can select the highlighted link above for more information and to begin making your reservation - it does book quickly during a race weekend.
I hope this helps, Maira! Please let me know if you should have any additional questions. I am here to help you plan a magical experience for the whole family.
Faith
