First of all, the better place for your research is the West Coast Departures board, here:

There are dozens of threads recommending hotels here. Take a look around.
Be aware, hotels in the downtown are not cheap during cruising season. The downtown is fairly walking friendly, so being close to Pike Place, which can drive up the price, isn't as important as you might think.
