I just got a bid accepted for Downtown Miami. I am traveling in March 2005 during Spring Break. Don't know if this was the reason, but I got a 65.00 bid accepted for Hyatt.
I started at 45.00 and bid in $5 increments every 3 days (the minimum # of days between the same bids). I guess because Spring Break time made it higher than the $35-$40 figure I see floating around all the time.
Still, it- by far- beats the $210 price tag on that hotel if I booked thru hotels.com or the like.
