I read that if you park yourself that you will have a huge flight of stairs to walk to get to the hotel. Is there a elevator too? I have really bad knees, and need to know if there is an alternative. Yeah, I know, I will be walking MILES while at US/IOA, but there is a world of difference between walking on flat ground and doing stairs when your knees are this bad. I may just have to use the valet service.
