How to get a free re-bid?

A free re-bid is adding a zone that has only up to a lower quality level than you are bidding, to a rejected bid. It is not adding a zone that just doesn't have the quality level you are bidding. It must be a zone that has only up to a lower quality level.

For re-bidding purposes (when your bid has been rejected), add a zone that has only up to a lower quality level than what you are bidding, because that just gives you a free re-bid for your original zone. In other words, if Zone B has only 1*, 2* and 3* hotels (or 1* and 2*), and your original bid for a 4* hotel in Zone A has been rejected, you can add Zone B as a free rebid to your Zone A offer. You will not get a hotel in Zone B because it does not offer 4* hotels. Of course when you add the zone, you'll need to increase your bid amount and not lower your original quality level. The Hotel Lists should never be used to determine your free re-bid zones for the reasons stated in the introductory comments on the Hotel Lists which you should read to learn how the Hotel Lists are compiled.

For purposes of free re-bidding, a zone with the highest level as Resort is only a free re-bid when bidding for a 5*. Bidding any lower than 5* and adding a zone that has Resort can result in what Priceline refers to as an upgrade to a Resort in the added zone.

In order to re-bid, you have to change at least one parameter of your bid. That could be adding a zone (as shown above), or changing the quality level, or changing the checkin or checkout date. Once you have exhausted all of those, you must wait 72 hours (not just 3 days and not 71-1/2 hours) before bidding again.
