Pike Place Market, Seattle Waterfront, Seattle Center

I always Love going to the Pike Place Market. Get fresh flowers, tons of local merchandise/art for sale, see actual salmon get tossed and close by is the Seattle Gum Wall.

You got to visit Pike Place Market and the first Original Starbucks in the world.

Are you active? The hiking here is amazing!
Visit Alki Beach Park and bring your walking shoes and take a long walk or rent bikes to ride on the beach walk. It's amazing.
Ferry ride to Bainbridge Island for lunch and a walk around.
MUSIC-- go to Dimitriou's Jazz Alley or check out what else is happening. Seattle's music scene never fails.

Pike Place Market, the Ballard Locks, The Spheres

Whale watching, dinner at the Space Needle and Pike Place Market!

Golden Gardens and Alki for beaches

Seattle Center is a must! 
Ride the Space Needle up to the observation deck. 
Museum of Pop Culture is awesome if you're a music lover.
Also check out the Seattle Waterfront and Pike Place Market :)

You'll definately want to do Pike Place Market before Noon.
The Space Needle and Seattle Aquarium!

That depends on what your interests are. Downtown there is Kerry Park, The Space Needle, Pike Place Market, and the Museum of Pop Culture. Oh, and the Chihuly Garden and Glass is a must see in my opinion. Leavenworth (Washington) is a worthwhile day trip and so is Paradise, Mount Rainier National Park. They are both equally awesome.
