I know nothing about tolls, but I can offer a little gas advice from a fellow van driver. We have a 1999 GMC Safari(basically a box on wheels) with a 25-gallon tank. If I leave home with a full tank, I get as far as Brunswick, GA, where the gas seems to be the cheapest(this is on 95). We like exit 29, but exits 14, 6, and 1 will do, too. The gas price is usually @ 10 cents cheaper at these exits...I paid $1.26 at exit 29 a few days ago. From Brunswick, it takes exactly half a tank to get to WDW(a little more if we get caught in construction delays...expect these between Daytona and Orlando). We usually drive to most parks, using about a fourth of a tank during most trips, and put $10 worth of gas in at the Exxon on Disney property (across from Downtown Disney). Gas here has been $1.59 for more than a month now, which is less than the gas stations near the Crossroads. If we leave Orlando with half a tank, we get back to exit 29 where we fill up again, and that gets us home. I currently get about 17-19 miles to the gallon...a little less than when I first bought the gas hog 4 years ago!
