I know you said you will be childfree but I just found out today that if you dine at the Dolphin Resort Bluezoo or Shula's Steakhouse that you get two hours of free childcare in their childcare center. They are open 5:30 pm to midnight and they feed the kids dinner. Extra hours are $10 per hour per child. There does not seem to be a limit on how many children you bring but you need advance reservations and they have to be potty trained, ages 4-12.
