I-75 is pretty well kept open and clean of snow. No bad mountains to contend with to speak of.
Make two trips, come on down in Sept/Oct stay a week or so, store your RV, drive back to that great "SNOW COUNTRY" then come back down at Christmas time to where you have your RV stored (plenty of places). Hook to it, off the Mickey Mouse Land. You might like it so much that you will stay a couple of months with us. You see, when you come down the first time you can make reservations for your second trip outside of Disney for your extended stay. Will give you plenty of time to get a good winter time tan!!!!!!!!!!!!
