Apparently, Priceline has changed the rating on the Curtis to a 3.5 star. I just bid $45 for the hotel including Denver Southwest and Northglenn using the advanced method of using free rebids. I bid all the way from $25 up to $45, so this was likely the lowest possible price. The Curtis is actually a fine hotel, a great location, and this is a great discount. However, I was hoping to find something with a pool, which is why I chose the 3.5 star rating. A little bummed that a rating change derailed my strategy.
