I have to drive to BWI and park my car there for 4 days. I was trying to figure out the most economical place to park. So far, it looks like the Long Term lot is cheapest at $8.00/day. I called The Parking Spot since we supposedly get a discount there and they quoted me a "discounted" rate of $9.55/day for SWA peeps...a lot higher than the $7.95 (+ tax) coupon rate on their website! Does anyone know of some cheaper options? Thanks!
