Headed to Edinburgh in August - primarily visiting to attend Fringe shows but will be exploring the city. We are there for 5 nights before renting a car and driving to Oban for 2 nights. We are planning to take the train to Stirling as a half-day trip, but were also thinking of doing a day in Glasgow. Most days we will want to be back around 17:00 or 18:00 in order to catch the shows we will be seeing. Is it worth it and doable to only do Glasgow (via train) for 6-8 hours? If yes, what do you recommend as top sights for a short visit?
We are getting the Two Together rail card; since Scotland has extended Off Peak through our trip, does that mean we can actually use the card on trips before 9:30AM during the week, or is the restriction still in place?
