Unbelievably cheap with the on-line coupons; one of the cheapest in the area. It's not hard to find, and the shuttles are reliable. The driver on the way to the airport was really polite; on the way back our driver was less so, but the service was tolerable. Like I said, it's nothing special, but if you just need a place to park your car for a while, this is a great place to go to. We were out of the state for two weeks and chose to leave our vehicle there. Two weeks is more than ample time for it to get scratched, stolen, or broken into, but when we got back to the parking lot, it was exactly as we had left it. If I need another parking service in the Seattle area, I'll probably go back, unless I can find a better deal (pretty unlikely).
Pros: Awesome Price
Cons: None really. The employees were a little brusque.
