I haven't used Priceline yet to bid for a hotel, but from what I understand: to get the most free rebids it's likely that I would have to close the browser several times to maximise the number of free rebids - does this mean that each time I would have to renter my credit card info, address etc each time I open a new browser window? Are there any benefits in registering with Priceline - for instance, are your credit cards/address details saved in Priceline so they are automatically generated after you have logged in and start bidding?
