We need to park at ATL for three weeks. Found airportparkinginc.com that arranges for parking at various hotels at as little as $3 per day. This is a prepaid arrangement and you just take the hotel's shuttle. Has anyone used this company? I am afraid of paying my money and driving to ATL day of flight and still having to go to Plan B. Other than this, the best deal that I have found (that has transportation to new International Terminal) is Parking Spot 2 at $8.95 per day less 25% coupon. Any better deals?

thanks,
