Mrs Mushroom's school will soon be receiving a French "exchange" teacher - she's booked herself to London St Pancras OK, but then hit a snag. It seems that the train companies she's tried won't sell her a ticket onwards to Leicester with payment on her "carte bancaire", presumably because she doesn't have a UK address.
Any ideas how she could buy a ticket to Leicester before arriving in London?
However, if she's coming by Eurostar, I'm mystified as to why she's booked to St Pancras when the Eurostar website allows passengers to book through tickets from Paris (or other principal stations in France) to Leicester. Perhaps she could contact Eurostar and change her ticket to London for one to Leicester?
