I am reading all I can but am having trouble sorting out which option might be better for us. Family of 4 (kids 13 & 15) and we will have the Family Card. 8 day trip flying into Zurich and heading to Lauterbrunnen for 4 nights, then Lucerne for 3 and back home from Zurich. Has anyone had any experience after taking excursions as to which one is most economical please? Thank you SO much for any advice on this!
