I didn't want to put this in the Hotel Bidding thread, because it's kind of a different issue.
For a priceline reservation, how much does the hotel "freeze" your credit card for incidentals?
On my last trip, the hotel froze my card for the amount of the PL res. So for the duration of my stay, I was basically paying double. Upon check-out, they restored my credit.
Is this common practice, to ensure that you aren't using a bogus card for the incidentals? If so, is there any guideline to determine the amount that will be "frozen," though not actually charged?
