My son has done the summer camps at Penn State for several years. He is always in East for a couple of weeks in the middle of July. We have brought a fan to be put in the window and another fan that stands on the desk. The cross breeze worked just fine and he didn’t have any issues. My daughter is going this summer for LEAP and we will do the two fan thing again. It’s only 6 weeks. Don’t let it deter you from your overall plans!
