Unfortunately, I'm not the go-to man for any of this information. >_> I mostly live and work in Geneva, and don't have much of a chance to get around. I've only been to Vienna once, and only for a couple of hours while we got something to eat. Munich was a nice town to visit, though. Prague is apparently nice to look at as well as being a pretty nice club spot.

That said, I recommend the Interlaken area if you happen to come to Switzerland--lots of mountains, lots of air, not too hot, from what I remember. If I can think of anything else, I'll add another comment.

Congratulations! And if you happen to stop by around Geneva, drop me a line. :-)
