You can visit as many countries as you wish !

The only restriction is that you cannot use your pass on more than 2 days in your own country.

If you'd like to make multiple trips with a single pass you'll have to buy a ticket from your hometown to the border point/first stop after the border.

Thank you so much for the quick answering. Now I have all informations I need to buy the pass. All the best to you
