Have to spend one night in Seattle for a 5:30 am flight- Will get there around 8p- so not much time but wondering if there is a hotel near the airport on on the grounds of the airport?

You don't mention a price range, comfort/luxury level or other amenities desired. If you just want a basic motel with a AAA 3-star rating, free wi-fi, free breakfast, free airport shuttle then you may be interested in the La Quinta Seattle-Seatac airport. Their phone number is 1-206-241-5211.

I have never stayed at these hotels, but have been inside for a meeting at DoubleTree and Red Lion. Nothing spectacular, close to the airport.

look at hotwire.com or do priceline.

Another strategy that usually yields good results for me is to book at a property of a brand at which I have previously had good experiences.
