I spent a lot of time bidding for 3.5*-4* hotels in Boston for 2-3 nights around 3/12/13. I'm from the Boston area, so I had fun playing with my "free bids," trying to get the best deal that would fit my needs. Because I didn't want to pay astronomical parking fees, I looked for a downtown hotel that is easily accessible by the T. I also placed many bids for under $50/night in zones like Cambridge West that I could justify taking a cab to or parking at. My first bid was $71 for the Boston Common - Theater District zone. Priceline offered me the option to increase my bid by something like $22 for an immediate rebid. I declined and decided to go with some really low-ball bids while slowly adding on more zones. Unfortunately, all of my low-ball bids starting in the low-40s and increasing $2-3/bid through the low-60s were not accepted. When I was running low on bids, I increased to the 70s but only bid in the downtown zones. When these were turned down, I did a new search, and decided to try for only 4* hotels in Boston Common - Theater District again, using the free bid trick (there are 5 zones in Boston without 4* hotels). I started bidding at $80, increasing $5 with each bid. My bid was finally accepted at the Omni Boston Parker House for $90. Seeing what others have gotten at the Omni, I feel that I could have gotten a better deal, maybe saving $20-$40 over the two nights if I hadn't been so antsy to get a bid accepted. Overall though, I can't complain. Priceline saved me 69% off of the Omni's published price.
