Just a reminder that off-peak rail fares are only £2 return from Bicester-Oxford (£1.80 Islip-Oxford). Compared to the bus (X5 is £4.50 Bicester-Oxford) or Park & Ride (at least £2.20 plus petrol costs and the chance of traffic jams on the A34), this represents excellent value for journeys into the centre of Oxford.
Parking is free all day to rail users in the Islip and Bicester Station Road car parks and also Bicester Village (Mon-Fri only bays marked for rail users).
