We will be in Scotland for a few days in late July with our 2 teenage boys.We fly into Manchester and are hoping to take the train to Scotland. I think we will make Edinburgh our base and would like ideas for day trips. We are possibly staying at Six Mary's Place but are concerned about the vegatarian food with our boys. From Edinburgh should we take set tours, hire a private guide or hire a car? Does the Sleeper Train to London run on Saturday night? Is that a reasonable way to travel to London and will we sleep at all? Thanks for any help and ideas you can provide.
