Having previously experienced the intermittent state of public transport in the Peak District we're looking at renting a car on our return.
Coming up from London, what would be the location with the best combination of convenience to the Peak District, on a train line and having one or more major car rental agencies, especially if they are within a short walk of the train station?
Derby looks like an initial contender, though Chesterfield and Sheffield were the two cities we went via last time, but I'm not sure what other options there are.
