Thanks Jerry, the information I am more interested in is recommendations (or not) of companies.

It is difficult just looking at websites to work out who is good or not (they all say they are excellent!) and wish to try to avoid a dispute, should one arise, across the "Pond".

Has anyone used or heard of "Supershuttle ExecuCar ". They seem to be the company that Expedia use, but I cannot access them until paying for the trip! ....Update, found them on Internet, anyone used them or know of them, please?

NB
