There are lots of parking options near SeaTac airport. I would recommend one that cares about its customers, not SeaTacPark. They recently canceled my reservation less than 24 hours before my flight, leaving me in a real bind. When I wrote them a letter to detail the terrible service I received, they ignored it. Park somewhere else, preferably someplace that honors its reservations!
Pros: None.
Cons: Terrible service, don't honor reservations.
