I don't know what you mean by getting a good price through the "name your own price" Priceline product. You don't know if your price that you named is accepted until you actually pull the trigger and commit your credit card to a non-refundable reservation.
I have been able to get GREAT rates through Priceline. I start bidding at 60% of the Hotwire rate for the same time period. I keep a little spread sheet to keep track of everything and my rebids. I also make sure I don't go over my back-up rate.
