I completely agree with tedtop43 and think Priceline is totally wrong on this issue.
As an example, there are many 3* and 3.5* hotels in the Disneyland/Anaheim area but currently about 90% of the bids in that zone are hijacked by Crown Plaza. They low ball Priceline bids then tack on a mandatory $12 “resort fee” at checkin. Never mind that you arrive by taxi and don’t have a computer and are not going to Disneyland. You are going to be hit with parking fees and internet access fees anyway.
I have written Priceline about this to no avail. It seems to me that accepted bids should include all mandatory charges. How else do we know if we're getting a good deal?
