Local renters are subject to differing vendor rules for renting vehicles. Some car companies will not rent vehicles from their airport locations without proof of a return airline ticket, or proof of a cruise ship ticket that coincides with the rental. At off-airport locations, locals may be asked for at least 2 additional forms of identification that may include proof of your address, they may need to be a certain age (possibly 25 years or older). Some exceptions may apply, and it is important to read the detailed instructions as you book your vehicle.
