Thanks for all of your help. After much consideration, I booked the first option I was given near the Space Needle, as it looked like I was going to end up at the Silver Cloud Stadium or Broadway which were just too far for me. I ended up with the Holiday Inn Express. I did not have high expectations, but I have to say I was pleasantly surprised. It was everything I needed for a one-night stay in Seattle, and the service was excellent. Parking was $10, and it was only a 10 minute walk from downtown. I will definitely use HOTWIRE again and refer to this site when doing so :)
