I just found a corporate number for Dollar. The codes BR0706. I booked a car on this at $18.72 a day in Vegas a couple weeks ago.

NO underage fee NO additional driver fee. And it was cheaper than the regular price on the website. Ohh, also, they didn't ask for ID. Apparently, thats just not Dollar's policy. Sometimes, though, I hear you have to remind them at the counter that the underage and additional driver fees are waived.

What I do is I make the reservation online (I think you have to?) and then call to confirm that the fees are waived. You can ask them to put it in the notes.

Ohh, BTW, the company is Ticket Attack Consulting.
