Priceline

Priceline has a lot going on, which might be a little daunting at first. But if you stick with it, you'll quickly realize how much money it may save you. At its most basic, you can just search for a place and have the hotel of your choice (after narrowing down the possibilities), but you can also take advantage of a Pricebreaker deal.

Priceline has grouped three hotels at a single price. All you have to do is click Choose, and the site will match you with one of them. The trick is that you have no idea which one you'll get. The savings are enormous, so it's worth a go if you're willing to be flexible. Other offers include Express Deals which are an exclusive collection of low prices, albeit of the non-refundable variety. Also, again, you don't know what you've got until you've booked.

Priceline, in addition to its nearly gambling-like aspect (albeit the outcomes are often very excellent), provides bundle packages of hotels, flights, and vehicles, or a mix of those with flexible reservations. It includes all of the essentials, but we love the possibility of obtaining an even better price with a little risk.
