We will pick up a car at London airport and then will take 4 days to drive to Edinburgh where we will pick up some friends for the rest of the trip. We are a couple, well-traveled and well-versed in driving in the UK...but would like to know some places we should visit, stop overnight...we like B&B's or small inns...and we could happily venture off the motorways. The first stop would be within 2 hours of the airport as we will take an overnight flight and that will be about all we can handle in terms of driving that day. Any advice, information would be most appreciated. Thank you!
