Jason U. - Elk Grove, CA
It worked! I fully expected to get to the ticket taker and have them ask me what the hell the sheet of paper with my confirmation number was for. But instead they looked at it, processed it and sent me on my way. $7 a day for that location (right across from the airport) was well worth it.
The shuttle coming "every ten minutes" isn't correct though, it wasn't close to that.
Everyone I dealt with was very nice..which is odd as usually ticket takers at parking lots are surly as hell.
