This will be my first time having to add an additional driver onto my reservation, thus I was wondering whether any of you folks had an experience with it. I'm a National Executive, and plan on adding a person who is under 25 as an additional driver on my reservation. This person lives in the same household as me, and we live on the same address as listed on our licenses. As an Exec, I typically just choose the car and drive away. However, in this case, am I required to stop by the counter to add his name onto the reservation? Would there be any fee associated with this? I tweeted @nationalcares- their answer was rather vague. States that if the person is >25, apparently he/she is "automatically authorized" to drive without a fee. Any help would be greatly appreciated!
