It a very nice place the only thing I’ve just spent so much money. He still have to pay for parking there and it gets back fast.

Coast Gateway Hotel
The room was very clean. The staff was very friendly, helpful and accommodating. They had a bag breakfast ready for us at 5:30am, when we were shuttled back to the airport because the breakfast bar wasn't open yet. It was very good and had a nice selection of items in it. It was a very pleasant experience ...

Country Inn & Suites by Radisson, Seattle-Tacoma International Airport, WA
Very clean room, the bathroom was nicely remodeled. It was a very basic and small room with not much space but fit the needs for a one night stay after a flight. The breakfast was not very enticing so I would recommend considering other options for breakfast if you wanted something healthy.
