What are the tours to fifteen European countries?

If it is a travel agency, I don't think it will include the four Nordic countries and Iceland. The cost is too high and the distance is too great. It should be some countries in continental Europe strung together by carts, including some small countries passing by. Britain may not include it, because Schengen can't sign into Britain, because you have to apply for a visa separately.

Looking at the European countries with relatively smooth cart pulling, it should be Belgium, Netherlands, France, Monaco, Italy, Vatican, San Marino, Austria, Hungary, Germany, Switzerland, Luxembourg, Liechtenstein, Spain and Portugal, which can be strung together without being particularly tired. Among them, Vatican, San Marino, Liechtenstein and Luxembourg are all small countries passing by. Count them in. If it is added, it will be Poland and Czech Republic at most, and the newly developed tourist routes in Eastern European countries in recent years are also quite distinctive.
