answer:If you will be there the whole summer (exciting) after a week you will feel very comfotable I think, have a better lay of the land and know how things work. The train can be very convenient and efficient. Here is a link. Most of the tourist things you might want to do will have directions from a train stop. Check the train passes available. Sometimes there are special deals for Americans if you are American. I know my parents when they were in Switzerland chose to stay centrally and Interlaken and then take day trips to the surrounding cities, but you will have more time to stay a few days in each place if you want. I recommend going to a book store and looking through the travel books. Sometimes that is more helpful than the internet tourism sites, or a good addition to help you feel more confident about what to expect. The travel books actually have the author telling you his experience, rather than an advertisement or tourism site. Although, it all is helpful. Fluther will be helpful too. I haven’t been to Europe in years but we have European jellies who will answer your Q I am sure.
