I am planning on booking the combined railaway offer to go to Bernina Glacier area starting from Tirano by Raetian trains. So I wonder if the railaway point to point ticket will be valid as:
1) A “day pass” for stops in between Tirano and my destination, in this case Bernina Diavolezza. So I can also visit other nice spots on this route.
2) A ticket for the famous Bernina Express train w/o Seat reservation, so I can decide if I want to use the panoramic service or the regular regional service and book the seat reservation myself on desired train and direction.
