100+ successful bids since May 2002.
Two disappointing bids, both at the 2* level, and both in Minneapolis.
One disappointment at the 3* level in Cleveland.
Most bids represented a 40%+ savings over rack rates. In general, a successful 3-3.5* big on Priceline is at roughly the same price as the local Motel 6.
With the relatively new 24 hour rebid rules, I generally do NOT rely much upon the two websites noted above, choosing to bid low, often real low and gradually increase.
