How do you buy hotel rooms online? Johnny Jet says you have to use a shotgun approach and go to several different sites. Priceline is great, but you want to go to Bidding For Travel. It's a forum that people use to report what hotels they wanted and what bids were accepted. Another is BetterBidding.com. The key to priceline is to go see what HotWire is offering and go 10% lower on Priceline. Bidding for travel is also good for car rentals on Priceline as well.
