have done the Stay and Scream multiple times. Not being a native Floridian, I find the temps at HHN to be rather hot. I don't understand it, but it seems to even get a little hotter at night, maybe its just me. Staying inside an air-conditioned restaurant seemed to be most important for me during the Stay and Scream waiting period. Of course everyone else has pretty much the same idea. Second choice would be a shady spot somewhere but I think you will find most of those will be occupied as well. I would recommend getting to one of the Stay and Scream areas early and securing a seat in a nice air-conditioned restaurant, grab something to eat and drink and wait comfortably. Its a nice respite before braving the HHN crowds and standing in lines.
