We're booking a last minute trip to Scotland August 20-25. We fly into EDI on the 21st (early morning). On the 21st night I have tickets to the Tattoo, and we have a hotel booked for the night of the 21st and the 22nd. That gives us two full days in Edinburgh to enjoy the Fringe Festival, etc.
We fly out of Glasgow on the morning of the 25th (10:30 am). We were wanting a nice feel for the countryside, and are considering renting a car for two days. We're wondering if it is reasonable to stay out of Edinburgh for the other two nights...maybe take the drive to Inverness, stay a night, then drive back to Glasgow for the night before departure? Or should we just stay in Edinburgh and do day trips out?
