Just a head's up - if the temps for Sunday keep sliding to the "hot" side, be prepared for Disney to do a fast start and release the corrals quickly to maximize the cool weather/darkness. That's what they did for the marathon in January. Usually it takes about an hour to get everyone started and they did it in 30 minutes.
So that means:
- GET TO YOUR CORRAL EARLY!!!! They were closing even the later corrals before the official start time.
- Those that have done the math and figured out approximately when you will be finishing for family members or how much of a cushion you might have on the balloon ladies, that could all go out the window. Have a back-up plan.
