I just got done spending 5 days in Zurich. I liked what was offered to me. I went to Hediland and Liechtenstein one day, toured a small town called Rosenwil on another, spent an entire day at their national museum on yet another, and spent my last doing a free walking tour and a day at the zoo!
I loved it! I was able to speak my limited German to a select few and thought I did ok, but need a lot more improvement. Most importantly, I made new friends. :-)
