Strange. I've been using PriceLine and this site for quite a few times, and always got great prices and accurate predictions of the bidding strategy. Not this time. Yesterday, I checked out your site for info, and then went to PriceLine (forgot to use your links). Looking for Toronto Downtown, 4*, Friday March 4th to Monday March 7, 2011 Bids: zone 5 Downtown Toronto South $65 -- Refused added Downtown Toronto North $70 -- Refused added zone 1 $75 -- Refused added zone 2 $80 -- Refused added zone 3 $82 -- Refused added zone 9 $87 -- Refused added zone 12 $91 -- Refused added zone 13 $98 -- Refused added zone 14 $107 -- Refused added zone 15 $117 -- Refused added zone 7 $127 -- Refused added zone 10 $137 -- Refused no more zones! Failed bidding I noticed that PriceLine was offering a "direct buy" for Thompson Hotel for $157. 24 hours later, today: Tried again, remembering to use your PRICELINE link. I tried aggressive bidding: zone 5 Downtown Toronto South $75-- Refused added Downtown Toronto North $90-- Refused added zone 1 $120-- Refused added zone 2 $135-- Refused added zone 3 $141-- Refused Added 3.5*, price of $80 --Changed my star level-- Refused added zone 9 $101-- Refused At this point, I gave up. I went to the PriceLine section where they give a list of hotels and chose the cheapest one available downtown. Thompson Toronto, US$157. No idea why it was all out of whack with what I normally pay, and the info on this site (which indicated it would be around $70-$85). Still, thanks for all the other times your site site helped me!
