Priceline
Special K, I have gone the Priceline route a few times, one has to have patience on the bidding process, but it's well worth the effort considering the savings.
I usually book 4* hotels in Montreal, and recently (last Nov), I was fortunate to have gotten Sofitel for part of my trip, that hotel is amazing, although the room is a bit crampy, but very luxurious. However, since I didn't get to choose the hotel at the time of bidding, Priceline included low quality hotel such as Hilton (Bon Adventure) in their of list of 4*, and unfortunately I was assigned to Hilton - a 2.5* hotel with a 4* pricetag, what a rip-off. How can you brand your hotel as a 4* if you don't even offer in-room Internet access?
Anyway, just a comment on Priceline and their screwed up hotel * classification system - you may not give what you expect.
Cheers,
