Every week a Guardian Money reader submits a question, and it’s up to you to help him or her out – a selection of the best answers will appear in next Saturday’s paper.

This week’s question:

I am 25, live in London and am going to the Edinburgh festival in August. The train (4.5 hrs) is £132 return, but a coach (10+ hrs) is a tempting £34 return. Just how grim are long-distance coach journeys? Should I cough up for the train?
