I have always booked through AAA, where the is never a question of age. I have looked at travelocity to make sure I was getting a good rate, but have definitely always booked through AAA where it doesn't ask. I have gone through the process of travelocity and havent been asked for an age, which is why I mentioned it.
The kiosk does ask for your license number, but not your age. I guess they could check it if they really wanted to, but it's not in the kiosk fine print that you need to be 25.
I didn't mean to hijack the thread or cause an argument about the moral dilemma of circumventing the age thing. The OP wanted to know if her DS was going to be able to drive or not, and the fee is huge, so I was offering help.
I'm sorry if you don't agree with it, but arguing about it isn't what this thread is for.
