In reply to Ally Smith:
Done that more than once, in the cafe with the nice pictures of the Matterhorn on the wall just before you head into the train station!
However, I've decided I actually like sleeping and I need wifi so I can dial into a conference call in the morning (. . . work is really, really pants isn't it!) So think I'll go for the F1 on the French side. I'll be hiring a car (and driving in France) so saves all the faff with the tolls etc.
Thanks all
