I have a question regarding multiple reservations. I currently have 2 reservations for Alamo through Costco (one for a standard car, one for an intermediate SUV). We are 2 adults and 2 children. We normally rent a minivan, but the price is way too high (pick up December 31). I'm wondering if I can keep both reservations, until I see what is in the lot in each aisle and then cancel. Has anyone done this (cancelled a reservation the day of pick up)? I'd prefer to get the biggest car for the lowest price (e.g. if an SUV or minivan happens to be in the full size car aisle), so I'm afraid to keep just one of the reservations. With my luck, I'd pay for the SUV, and there would be SUVs or minivans in the full size aisle...
