Note - this is merely ordering tickets online with about a 5 service fee to Viator. Bürgenstock is pretty and maybe there is more to do and see in the summer, but definitely not spring May. The Hammetschwand Lift is a 20 minute walk/hike from the resort where you are dropped off. The funicular is steep as advertised. If you can get out to the lift, it is neat, Otherwise, it is just an OK day and purchasing through Viator doesn't do much for you. Everyone seemed confused when I showed them the voucher instead of a ticket.
