Now this might not be true all the time but I have made 3 hotel bookings in last 2 weeks. Though I was keeping an eye on prices for over 5 weeks. I noticed there is curve. Essentially, if the hotel has availability closer to the date, they try to unload those rooms at a lower price than say 3-4 weeks prior. I say just hang in tight. And to verify my theory, check on the 08/02-08/04 Seattle Downtown Pike Place hotel 4*, prices for next few days. I am betting they would be lower than what I paid - $138. For example the price for your dates $191 right now is either Sheraton or Westin and I got both of them for <$150. Just make sure there are no Events in the city for the dates of interest. You can ask fols in seattle forum on tripadvisor. Good luck.
