We stayed here after arriving at SEA on the weekend. The shuttle picked us up less than 20 minutes after calling (not a lot of traffic late at night) and we were soon checking in. The nice desk clerk described the room location, just what I had asked for in the reservation. I got the 250 point bonus on the "wheel of fortune" spin, we helped ourselves to goodies out of their Halloween candy dish (peanut M&Ms, yum) and then headed for bed. The king bed was clean and comfortable and we slept well. The shower the next morning had good water pressure and breakfast was standard SS issue with a nice assortment of toppings for the oatmeal.
The only negatives in the room were a fairly weak fan on the HVAC unit and some stains on the curtains. The fan probably wouldn't have been an issue if we had arrived earlier and the room had had time to get to the temperature we wanted before bedtime.
We'd stay there again. This time we had started our trip with a Park N Fly rate at the Hilton Garden Inn next door so we just got our car from the lot next door and took off. Next time if the SS has a decent Park N Fly rate we may start and finish there.
