I always give 1-star to Hotels that accept anonymous Priceline bids and then charge extra "resort fees" when you show up.
That's fine if you want to hide fees from window shoppers to make your sticker price look lower than it really is. Let them dig through your fine print and decide to stay elsewhere if they so choose.
But to accept anonymous bids from services such as Priceline where customers have zero visibility into your extra fees until their credit card has already been charged is unethical ( and you know it ). I suspect that the law hasn't caught up to this new modern flavor of bait and switch that you folks in the Hotel business are experimenting with. Enjoy ripping people off while the party lasts.
