On the day we travel by train from York to Edinburgh, my daughters and I plan to spend the day stopping to explore Hadrian's Wall. While we've looked into Rabbie's and Peter Carney's tours (recommended by many) and several other tour companies, we'd really like to go at our own pace for the day. We'd like to walk some, visit the museums and enjoy the entire atmosphere. I have looked into renting a car between Carlisle and Newcastle and have found Hertz does have locations at both. The direction (east or west) along the wall doesn't matter to us. We'll be arriving and departing by train. The Hertz locations look to be at a distance from the train stations.
Does anyone have any experience with renting a car for one day between Carlisle and Newcastle, with a drop off at the other end of the wall? Looking for assistance in determining exactly where we'd be able to pick up and drop off the car, without having to hire a taxi to get us to/from the train stations! Or other alternatives? If you've traveled with Peter Carney, does he allow you to tell him your itinerary and he just drives and gives his expertise where applicable? It sounds a bit more formal than that.
Thanks to all, in advance!
