We are planning to travel in the month of September to Lucerne for 4 days. Planning to do the Jungfrau, Mt Titlis, Interlaken and Mt Pilatus excursions from Lucerne. Please can somebody advise if it is possible to buy the golden trip ticket to Mt Pilatus and for the other excursions on the same day from the Lucerne tourist office. I have read in the Lucerne tourist office website that tickets needs to be purchased atleast 10 days in advance. Is it true? or can it be purchased on the same day in the morning?
