the only difference with them is one is "covered indoor" parking and one is not. charlie browns the last few times had the car ready and waiting for us when we got there. it was warmed up (In the winter) and the other time it was cooled off with the ac when they shuttle van brought us back to the car. for the 50 cent difference in fees I usually just park at the airport now so this way I don't have to wait for the shuttles to come pick us up. its 5.75 a day for the extended term parking and its been 5.25 for charlie brown and park n fly. they do periodically run coupons in the sunday paper for their lots.
