Thanks for the reply. I think Brevard County would be a different story for us. We had a place in Palm Bay, and if we were living there now I'm confident that it wouldn't affect our DVC membership at all. It's only 80 miles away, but after a long day at the parks an 80 mile drive is too much. We might as well be living in Georgia. But we are going to be living in Kissimmee, literally three right turns from the main gate - rarely if ever more than a 22 minute drive home from any of the theme park parking lots (according to Google Maps).
I wonder if the lack of replies from DVC owners who live in Orange, Osceola, Polk or Lake County indicates something important to me, though.
