I was wondering if I can travel within the same country, for example travel from Rome to Venice, with my Global continuous pass. Also what happens if I decide to stay in Venice for a few days before going to Paris? do I have to use this pass "continuously" ?
A global pass can be used within or between countries. Within the period of validity, it can be used every day or once a week or once every two weeks if you so choose - but of course most people would not buy a pass for such limited use. You can and should stay in Venice for more than a day. What sort of silly vacation would it be if you were required to hop on a train every day?
