Hello,
I have been to London three times and although I love it I wanted to see some countryside and maybe a castle this time around. I have never been to Scotland and would love to see that. I have the rough outline of flying from Phx to Edinburgh arriving Oct 9th in the evening. Having all day the 10th and 11th for Edinburgh (let me know if that's too much time). Morning of 12th acquire the rental car and drive to see Hadrian's Wall section at Birdoswalk. Spend some time there and drive over to Keswick for hotel and looking around. Wake up in the morning of the 13th and go for a morning hike at one of the nearby lakes and in the afternoon drive to the Cotswolds area. Then the 14th and 15th would be for exploring the Cotswolds. Morning of 16th leave early and drive to Heathrow to fly for 1440 flight home. (is it easily possible to be at airport by 11-12?).
I realize this is a very vague plan but just a rough outline. I am an over planner by nature and am trying to keep this somewhat open to spontaneity (as much as it bothers me). I wanted to visit York too but thought this might be too much in this amount of days. Let me know if this is way too much to do and too much driving. I appreciate any help
