If you have a 15-day opportunity to travel freely in Europe, which countries are you going to visit (no more than 10 countries) and make corresponding strategies?

Hello, as a senior tourism practitioner, let me answer your questions. If you have 15 days to travel freely in Europe, you should only go to three countries: France, Switzerland and Italy. If you feel that there are too few, you can add Germany at most. Don’t be too greedy and choose more countries. . Remember, what you want is free travel, a relaxing trip, not a casual trip, so you must not choose too many countries. The countries I chose have convenient transportation and easy guides. They each have their own characteristics and are all representative of Europe. If you play these countries thoroughly, you will be able to play almost as much in Europe. Switzerland represents the scenery, Italy represents the humanities, France has both, including food, beautiful scenery, shopping, culture, and geography, and finally Germany can be used as a powerful filler.
