I had seen that others had won the Hilton and Hyatt for $55, so few days ago I bid $52-58 in $2 increments for a 4* ORD hotel (10/2-3) with no success. When I bid several days ago, the Hotwire price for a 4* ORD hotel had been $101. This morning, I noticed that the Hotwire price for a 4* hotel (including golf, so probably the Westin) had dropped to $85. I suspected there might be new Priceline inventory at a lower price so I bid again on Priceline. Got the Westin on my first bid of $54. The all-in price was $69.50. Given the Priceline hotel prices these days, I'm happy with this price, but I possibly could have gotten it for less, so I would encourage other bidders to start below $54.
