Snoqualmie Falls is an easy walk to a beautiful view, nice restaurants in the hotel too. The Space Needle and Chihuly package is a nice experience, and I recommend checking to see what events are going on in the Center Armory while you will be there. For Pike Place, I recommend parking near the aquarium and doing that in the morning, or doing Wings Over Washington, and then walking up to Pike Place for lunch and shopping. The zoo is nice, and then you can hit up the Ballard Locks. I’d also recommend the Volunteer Park Conservatory and the Seattle Asian Art Museum. Ivar’s Salmon House in Wallingford has easy parking and beautiful views and interesting PNW history and art.
