Gotthard bernina circular tour
Hello,I managed to book the Gotthard circular tour in Switzerland by phone call, because it seems this tour in specific wasn't ready online.The tour does a roundtrip from Zurich main station to Chur, Tirano, then Lugano and finally back to Zurich. The web page https://www.rhb.ch/en/tickets-travelcards/promotions/gotthard-bernina-rundreise#info Says: "The price includes the ticket for the entire stretch" , but we exchanged the dossier number we were given for the tour tickets, and the tickets don't include Zurich to Chur nor Lugano - Zurich, hence my questions: Do we have to add Zurich - Chur, Lugano - Zurich to the interrail pass and consume one day from our travel pass?Or did we miss something?
