Seatac Park is a pretty good operation. It’s one of the more value oriented parking lots. They frequently offer discounts and have some of the better rates for Seattle airport parking. There are some downsides though. They’re pretty much the farthest from the airport, though its still only maybe a 5 – 8 minute shuttle ride. It’s also an outdoor lot so you car sits in the weather. In the summer you might come back to find the interior of your vehicle is 100 degrees. In the winter you may have to load luggage in the rain.
This Seattle airport parking business doesn’t offer a true valet service. Basically their shuttle buses come to you, and drop you off at your car. This works almost as good as a valet service, unless the weather is bad.
They seems to have quit a few buses running to and from the airport. Perhaps not quite as many as MasterPark, but still a decent amount. In their favor, Seatac Park only has one parking lot so any of their buses will get you back to your car.
