I'm looking to ride the Cotswold Line in full in one direction from Wigan over the upcoming half-term for the best value. I assume Charlbury or Oxford would count as 'destinations' in this sense as there is no applicable rover to help me here. I have a 26-30 railcard and could travel any day of the week apart from a Sunday. I'd like the best walk-up price and I'm more than happy to leave Wigan on the first southbound (WCML) train of the day if need be. I'm fine with splits. Thanks.
