Cheng,
Is this a business or pleasure trip or both? Geneva sounds like a lot of fun because of its location on the Lake. Let us know what you think of the place because neither of us have been there even though Hubby was born in Austria.
We could not afford to spend the night there with the weak dollar in 1978, so Mom and I just rode trains on our Eurail passes around Switzerland a few times and got off for a couple of lunches. Back then you could choose an all night train trip as your sleeping place instead of a hotel, and we spent a lot of nights sleeping on trains those 3 weeks. That was the only way we could afford Europe. And we did see some very interesting scenes on the rails and in the stations, especially in Scandanavia.
Enjoy the rest of your trip; we usually only shop for small artsy pieces because it is so hard to bring things home and prices are so expensive in most places outside of the US.
Cheers, Pgal
