"(George who I play with at the Sandy Bells session on Sundays lives next to the crematorium, and he often walks in to town for the session, but it's downhill and he's keener on walking than most)."

Edinburgh has arguably the best bus service in the UK. During festival time add 30 mins. on to any journey 'across' town, even walking, as the pavements can be just as busy. It just gets that busy in town. If you're camped at Mortonhall, Lothian Buses usually have a bus stationed near the camp site where you can get information about the buses, times etc. and also buy tickets in advance so you're ready to roll. The night bus (Lothian Buses 37) which passes within about ten minutes walk from Mortonhall Camp Site is every 30 mins. at weekends and every hour Monday to Friday. Don't get caught out, the day ticket doesn't cover you for the night bus. If you're camped further out on that route then use Straiton Park and Ride. Parking is free, but no drinking!
