Weekend rates of 4* hotels in downtown Houston and Dallas have long been in the low $40s on Priceline. But don't forget there's about a $10-11 tax/fees on top of the winning bids.

$42-44 are usually what people are getting. $41 is better than average. :D The proper way to bid 4* in Houston/Dallas is to start at $40 and then go up $1 at a time.
