Using the airport north exit, left at first light, go just over a mile on a side road to next light where you take two quick lefts to get on Route 528, you then pay just one 75 cent toll. Exact change not required.
Returning to airport via I-4 East to 528, get off 528 at exit 9 Tradeport, left and cross under, (cheap gas station right there), get into middle lane, required right onto McCoy, just over a mile on a side road to next light and turn right to enter airport. Again, one 75 cent toll.
