If I understand the Routeing Guide correctly, an 'any permitted' ticket from Didcot to Cheltenham should be valid not only via Bristol Parkway, but also via Temple Meads -- map LG shows a route via a Bristol routeing group that includes Temple Meads and Parkway. I haven't checked for dis-easements, but NRE shows a £25.60 fare (which according to BRFares.com is the Any Permitted Super Offpeak single) for the journey I wish to make (leaving Didcot at 07.12 on a Saturday).
Are on-train staff likely to be aware of this? (as I don't plan to break the journey, I'm less concerned about barrier staff). If there's any risk that they won't be, what exactly is it best to print out to show them?
As I intend to come back via Stroud, I could presumably save a few pounds by buying a route Stroud return ticket and excessing it, rather than an Any Permitted return. Is this something the ticket office at Didcot are likely to be able to do with a minimum of fuss or delay? And is the answer to that affected by whether I buy the ticket and the excess together or turn up with a ticket that I've already bought?
