Of course, what the state of Washington has to offer isn't just limited to what you can do inside the Seattle city limits. Beyond the usual suspects, consider a side trip to Mount Rainier National Park, which is a bit of a drive from Seattle, but well worth the effort. Or if you have even more time, this state-run tourist information site has plenty on tap for tourists looking venture beyond the boundaries of Seattle itself.

Apart from the usual rental cars, and taxis, you may want to take a public bus around downtown, as you’ll find that as long as you stay within a designated area in the center of the city, bus rides are completely free. 
Of course, the method of transportation in Seattle that is practically an attraction in itself is the Seattle Monorail. This remnant of the Worlds Fair runs every ten minutes between Westlake Canter at 5th and Pine and Seattle Center. It’s just a one-mile trip, and you’re only on board for about two minutes, but this is definitely one of those “getting there is half the fun” kind of things to do. Renting a car and driving in Seattle isn’t that problematic, but there are a couple of things you need to be aware of. One, there are a lot of one-way streets in the central part of the city, so you need to be very mindful of all the posted signs, especially if you are heading through downtown. Second, parking downtown tends to be limited and expensive, so you might be better off leaving the car in the hotel lot and using the buses and monorail to move through the city. If you want to just bypass the downtown area altogether, then your ticket is the Alaskan Way viaduct, which runs parallel to the Elliot Bay waterfront.

"Metronatural" is the new slogan of the folks at the CVB here in Seattle. And their website is a great little resource for visitors and convention planners. Among the highlights of the website are travel tips, ten things you "MUST" do in Seattle, and an interactive travel planning guide. The city of Seattle has a tourist and visitors' section of their local website as well, but it's a little less flashing than the CVB guide.

This little website is a little light on the details for each site, but the key draw here is the the coupon book that you can download for savings on some of the city's big-time attractions, like the Space Needle, the Underground Tour, Argosy Cruises, and the Woodland Park Zoo. The Online Seattle Travel Guide is another simple site with a discount or two available for visitors as well.
