I have done a search of this topic and have seen many conflicting answers and stories so I am starting a new topic. We are renting from Alamo at MCO. 3 days later we are meeting up with my Father in Law and wish to add him to the reservation at the car care center. My rental contract states there is a "free additional driver". I found this on the website and I am reading this to mean that as long as my Father in Law is an Insider member (we are too ) then he can be added for free. This in the info copied directly from the Alamo site. Would you interpret it the same way?
