Hi all, need some help. Am travelling to Switzerland for 8 days. Spending 3 days in Zurich, 2 in Luzern and 3 days in Grindenwald. So will be taking the trains from Zurich to Luzern, then Luzern to Grindenwald, then Grindenwald back to Zurich. During the stays in each of the places, will be taking trams etc. Would it be cheaper to book individually per trip or purchase the 8 day Swiss Travel pass? I know it would be more convenient but the travel pass equates to about 80 swiss francs per day
