Since I had lots of time thought I'd try low (just in case :) And I wasn't sure how low I would get two rooms. First bid: $80 rejected Second bid: $85 rejected Got two rooms for three nights for $651 at the Hyatt Regency! Couldn't do it without the site. Thanks! Also wanted to note that I was shocked when offered to add another night at that price in a box below my confirmation.
