Seeing the country where the chocolate comes from

My girlfriends and I really love chocolate, especially Swiss chocolate, so we decided we wanted to see the country where this delicious chocolate comes from. Now we are planning a trip. We would like to be able to tour someplace where they make chocolate, but if we can’t do that, at least we can see some of Switzerland, which looks like a beautiful country. Can anyone advise us on some good hotels in Switzerland that aren’t too expensive? We would like to see the Alps, and we would like to see Zurich as well. Any advice on things we can’t miss would be welcome.
