I have stayed at the property numerous times as a Hilton and a Sheraton. Most recently in April of this year.
First, even as a Hilton you got an appetizer coupon and the buffet breakfast. The appetizers are pretty good.
Second I find it incredible the lounge is closed for renovations. It is a new lounge converted from two rooms. My guess it really is closed for summer to save money.
The rooms on the club floor are OK. My biggest complaint is the shower heads in the tubs are only about 5 feet from the bottom of the tub. I aming over 6 feet and that makes it hard for me to get shampoo out of my hair.
One of the cheapest SPG stays in the Seattle area. Easy highway access (as previously discussed). Free parking.
I stay there every time I am in Seattle.
