I think of all the brands, Hilton is as good as any in putting the parking charges for each property on the website. There are properties where parking costs a fortune, but a few minutes googling can often get you a local parking lot that's open 24 hours a day for less money.

At one NYC hotel, you can pay $60 to park there overnight, or less than a block away pay $37 (or as much as $135). The choice is yours.
