One ticket for sale! Depending on whether I can persuade my mates to share with the lucky applicant, this'll come with a single bed in a 4 berth s/c unit, in which case I'll charge what I paid for it (i.e. face value + booking fee). If, on the other hand, you want ticket only and already have a place to crash (that would be a lot easier, owing to key constraints etc.), then I'll let you have it at a significant discount.
Plus I may be able to offer a lift from the Oxford/Aylesbury area, for petrol money.
Let me know!
