We have 6 nights to do with what we please in or near Scotland in August. We plan to fly to Edinburgh, but have been told that 6 nights is too long to just spend there. Therefore, we were considering 2-3 nights in Edinburgh and traveling elsewhere for the additional 3-4 nights.
Things we have considered are a couple of nights somewhere outside of Edinburgh with nice accommodations. We even talked about flying to Dublin for a couple of nights. Nothing is off the table and we are looking for suggestions. We have never been to Scotland or Ireland, so it would all be new to us. We will hire a car if needed. Our only limitation is that we need to be at London Heathrow by around 9AM on the morning after our 6th night, so we need to finish our travels close to an airport where we can get an early flight.
