I had a good experience with Fast Park & Relax. I usually take the Van to MCO but I wanted to try an off airport parking place very close to MCO. Five days of parking cost a total of $47.50. Tolls came to $11.38 round trip and I used four gallons of gas.
It's very secure and well organized. You lock your car and keep the key.
