We are heading to Disney at the end of June and my son really wants to go to Kennedy Space Center. So...Im thinking we will rent a car for a day and go offsite. We are staying at the Beach Club so the Alamo rental office is near by. Has anyone done this before? Did you just book when you got there or book online ahead of time? We have AAA but not sure if that would help. Any information would be great. Thanks so much
