We are newbies from Michigan. We have been in our 34 ft Class A Holiday Rambler now for 1 month, working our way south to warmer weather, and visiting friends and family along the way. We are in Titusville KOA now, have visited the Kennedy Space Center and now would like to visit the Keys. Any suggestions? We have a toad, can we park the rv somewhere and drive into the Keys? My husband is not sure he wants to drive the rv on the long high bridge...
