I've looked at the National web site and can't seem to find this answer. We've booked a car (at the low rate in March) and indicated we'd be picking it up at 12:30 pm. I'm now starting to look into plane reservations and the earliest we can get into Orlando is 7:30 pm (great rates on Air Tran out of Pittsburg - $310.00 round trip non-stop for 2 of us). Will they hold the car? I don't want to cancel and re-book because the rates are considerably higher and I don't want to change the time because then I'll have to go to the counter. I know I probably should have waited to book the car after the plane but I couldn't pass up the great deal ($131.83 for a full size for 7 days). So my question is...will they hold the car for us? Thanks in advance for your replies.
