Went to the train station and found out that I can get a train ticket for the same price on the day I travel. So there is still time for someone to come forward if they have room in the car, etc.

But it does look like I'll be traveling by train to Banbury.

Thanks to everyone who did try to sort it out for me. I really appreciate the effort and I do understand that sometimes the circumstances don't work out.

All the best,
Debra Cowan
