I am at the LV rental facility. I booked a car through the costco website for Budget RAC. Beware, Budget now requires to see your costco card (or amex costco cc) to verify that you are a valid member in order to get the costco rental rates. Make sure that you have your costco card if you reserve a car for budget through costco travel. Luckily I brought along my costco card so I was okay. The couple next to me wasn't as lucky. But after a lot of complaining the manager finally allowed them some leeway (they printed out their reservation but budget still didn't accept the reservation wo a costo card) and gave them the costco rate. I think in the future you may not be as fortunate if you don't bring along your costco card. Not sure about the other rental agencies but confirmed that budget now checks for your costco card (they have to reply on their system that they verified costco card.). the budget manager said that people were using other's costco numbers so now they require verification of card to allow discounts. sorry, I tried to create a new thread in the getting around forum but was unable (vmb said that I didn't have access to that thread). It could be a connection problem, I am using mccarren's wifi and notice some other problems with vmb. anyway, will post when I find a better connection.
