Ok our reservation is coming up tomorrow night - I am the one with the credit card and alamo insiders club info in my name so that is how I reserved the car was in my name. I had thought I read somewhere that you can add an aditional driver for free - but when I went online to fill out the "save time" feature - it added 99.00 to my reservation!? Is it free or not to add another driver? How should I do that? Advice?!
