That's a good point. I didn't think about using HHonors pts or AA pts. With all the points I have and all the money I spend on Hertz, it's annoying that I have to use my airline points to get a car for my family. Seriously....
alxir, I've known people who change the address on their profile to match the person's who is getting the car. Then whoever picks up the car has to pretend like he/she is your spouse. If you're ballsy, that's another option.
