I'm traveling to Lucerne Switzerland in June. Anybody have any good suggestion for excursions and food? My wife and I will be there for 4 nights and 2 full days (we arrive at 6:40pm on first day and leave on the fourth day at 12:45pm) before heading on to Paris. We would like to take a boat ride (lunch or dinner cruise) on Lake Lucerne, but are open to any great adventure. Thanks
