No, you won't want a visa. You have not stated while you were going, but i'm assuming it's not in the course of iciness. As others have said, this shall be tiring so it's satisfactory to hold your locations in close proximity. In Switzerland, you will have to go to Zurich. You definitely ought to go to Paris and Venice, which leaves 2 places. I might say both Florence for the mighty artwork, museums and structure, Marseilles to be able to see the city, swim and see the French Riviera, Barcelona for the robust city and the Spanish seashores, Milan for the sights and the fashion, Vienna for the fact that it is usually a lovely metropolis, very grand and with tons to do, or Berlin for the attractions (although this one may be somewhat too out of the way). If you want to see extra of Switzerland, Geneva is also high-quality, followed by way of Basel and Bern. Nevertheless, I suppose that the opposite cities I listed are nicer. Appear on the record and spot what appeals to you essentially the most, then make a determination. For me personally, it will must be Florence/Barcelona/Marseilles (three-manner tie)>Vienna>Milan, however it's your decision. They're all on the record for a intent. Revel in your holiday :) Edit: I forgot to add that Marseilles and the French Riviera is handiest worth it if you're going for the duration of the summer time, or the water is not going to be heat adequate to swim.
