Be sure your hotel reference prices are realistic. On the new year weekend I was able to Priceline a 3.5-star SPG place in BNA that had $142 listed on their own website, for $35+10 ($140 a-i for 3 nights). It's all supply/demand and I'm sure was made possible by not that many business travelers on that weekend. Still, sometimes you luck into a big dip like that on the blind sites that makes paying cash worthwhile.
