Booked a rental car for 7 days, but had to change travel plans because of health issue. wanted to delay picking up the rental car for 48 hrs and called the rental car company. Was informed I had to call Hotwire and then discovered thru a fairly obnoxious representative that no changes were allowed and booking was "final". Upon review of internet invoice, it stated sale was "final" and no changes allowed, but was not obvious or conspicuous. I would never book anything again with Hotwire. I am letting AMEX deal with these morons and AMEX will submit the letter from my treating physician. read full review »
