I would also add...
There are two National car places. one in road town and one between sea cow and WE. you may find that you are told to go to one, only to be told "we have to drive to the other one"
In our case we reserved at the one towards WE, only to be given a 1/2 hour drive in "rush hours" to pick up in RT. yes on certain days they have a "traffic jam". and then had to drive the really nice lady back to WE.
When we dropped off at ~WE, we were told we had to be driven back to RT because thats were "the car was needed". but our ferry left from WE.
tie down the details.
