I am going to be in Seattle one night leaving on the Amtrak train early in the morning. I have tried a few bids without success. It looks like the 3.5* rooms are over $100 for 8/17 Friday night. If I wait until the last minute, I have a backup hotel, would it be likely the prices will drop? When bidding at the last minute what would last minute bidding be, 3 days before or the week before? Otherwise what would you recommend bidding for a 2.5* in the downtown area (Pike Place). We want to be somewhat close to the Amtrak Station on King St.
