If you are leaving Magic Kingdom on a warm day, there is a fully air conditioned exit located along the right hand side of Main Street! If you enter through the store marked “Hall of Champions” (pictured below) you can walk through the connecting stores straight out to the front of Magic Kingdom.
Check out the map below for a reference of where this Air Conditioned passage takes you! The stores appear to be separated from the front, but they are all connected on the inside!
Disclaimer: this may not be a good idea with kids at the end of the day, as the “I want…” battle can be caused by walking through a LONG store!
