Hi Luiza,
Thanks for visiting the Moms Panel, and how exciting you are thinking of running the Princess Half Marathon!
Kids Nite Out does offer 24-hour in room babysitting service, and would be more than happy to come to your resort at 3:30 A.M.!
I inquired about the rates for this service, and this is what I've learned. Currently the rate is $16/per hour for the first child (four hour minimum), however since you would be requesting an "early start" (service starting prior to 6:30 A.M.) there would be an additional $2/hour surcharge, or $18/hour for the first child. Each additional child would be an additional $2.50/child per hour. The four hour minimum still applies, and rates are subject to change.
I suggest making the reservations as soon as your reach the 90-day booking window. This is done by calling 407-828-0920. You can visit their website at
www.kidsniteout.com.
Hope this helps, good luck!
