rail to Zurich - any ideas?

[captainmummy]

I have a weekend in Zurich coming up with 3 girlfriends, but one of them (Ok 2 if you include me) dont really like flying. So we were thinking of going by train. Problem is that the train is about £200, flying is about £100. How can we go green???
Any ideas for cheap travel?

are there any group tickets?

Have a look at www.seat61.com

Yep had a look at seat61 - it's a great site, but still comes in at £200.
Cupsoftea - I don't think 4 counts as a group, but thanks anyway. I think we'll have to fly, which is a shame as I'd like to go through the country not just over it!
