There is a 50 cents exit toll requiring exact change at that exit.Yes at the Landstar exit there are 2 gas stations about 1/2 mile from the exit. Get off the highway and turn right to get to the gas stations. Landstar is the last exit on 417 before you get to the airport
This is what we do as well, always gas up across from the BWV and have not once in 18 years been charged for gas.I have always filled up on WDW property before driving back to the airport via 417. I have never had a problem returning the car, the gas gauge always reads full.
