My husband and I are flying into Edinburgh and renting a car. Our itinerary is: Day 1 - Arrive in Edinburgh, Day 2 - Explore Edinburgh, Day 3 - Drive to the Highlands, Day 4 - Loch Ness and surrounding areas, Day 5 - Isle of Skye, Day 6 - Drive back to Edinburgh. We're looking for advice on must-see spots, hidden gems, and any tips for driving in Scotland. Also, if anyone has suggestions for cozy accommodations along the way, that would be great!
