Hi there

I will be staying in Cambridge and currently am looking for the most convenient way to go on a day trip to Oxford. Sadly a shuttle service seems to have seized operations in 06. (?)

I will have a rental car, but it is a rather long drive.

So, what are my options? Train, bus, car? What is the best?

Also: are there any air taxi operators I could use for a (relatively) reasonable price?

Your advice is appreciated.

edit:
I definitely wont be changing two or even three times when using the train, and I will not spend 3 hours + on a bus either. So it's either air taxi or car.

I can't believe there is no proper connection between those two cities.
