I have been using the free rebid method on priceline for 15 years now.
My best scores were 4 star rooms in NYC, Paris, and Amsterdam for under $100 a night and the huge Hilton in DT LA for $50 (where they filmed the famous scene in True Lies involving a horse and helicopter. Great movie.)
Those deals are long gone however, and the past year priceline instant deals have been better than bidding, but still not that great.
