Doesn't matter. When you pick up the car, just tell them that you want to drop it off at the other location. They will charge you an additional fee, something like $15, I think. We have really enjoyed working with National for several trips now and they just make it so easy. In addition to the EIS and Road Town locations, they also have locations at Long Bay and West End.

National will take care of you. If you want to make sure you are covered in advance, just call them. They are very nice and helpful on the phone.
