Milton Keynes - Dorchester South

Morning all, I’m looking to go from MKC - DCH and back tomorrow, arriving by 1300 and leaving Dorchester after 1730. I think that my cheapest option is to get a Travelcard (probably VTWC only) and then a BZ6-DCH off-peak return, is this correct? I don’t really want to go via Kensington Olympia but via Euston as its quicker (and presumably a Network Railcard will help in this respect).
Thanks in advance for your help

As you are asking on the day before travel, I think you have probably identified the best option. The ticket from BZ6 to Dorchester stations will be a super offpeak day return. And yes, a Network Railcard will discount both tickets and almost pay for itself on this one journey.

Good stuff, thanks very much for your speedy response Romilly, appreciated
