Your Seattle hotel tax rate is a perfect example of why checking the hotel's website is the best source and less likely to contain errors.(i don't have any answers for you regarding how your Seattle stay was accepted, excpept to say that maybe there are a few properties that actually pay Priceline a booking fee (which Priceline is willing to subsidize your bid with) or something else along those lines). I'm certain the hotels know their competition in the area, which includes knowing their rack rates, discounted rates, Priceline rates, Hotwire rates, etc. and adjust set their own rates accordingly. My understanding is that Priceline bids are rotated among hotels, so in your example, Hotel A is given first crack at accepting a bid in their zone, if the user's bid isn't high enough, then Priceline will check other hotels in the zone. The next user that places a bid (i suspect not counting re-bids by the same user) is attempted to get filled by Hotel B, and if the bid is too low, then it's checked against other hotels in the area. Next user's bid is first checked against Hotel C, and so-on. This is getting off topic from the original post, but i didn't move it as it would have made no sense (from a continuity point of view) if any of these were posts were at the beginning of a thread. So let's end dicussion here, but if you'd like to continue it, then start a new thread in the Questions and Suggestions category.
