My wife and our third kids (10, 8, and 6) are planning a trip to Germany, France, and England. We are spending a few days in London before heading up to Leeds to visit some friends who recently moved there. We will use public transport in London but we need a rental car when in Leeds to get around. We'll be heading up to Leeds on July 19 and returning on July 22 to catch our flight home from Heathrow.
I am trying to figure out the best way to get from London to Leeds and back - should we rent a car in London and drive round trip? Or does it make more sense to take a train from London, hire a car in Leeds, and train back to Heathrow for our flight home?
