Me and my husband are going to Switzerland May 5-May 20th. We will be flying into Zurich and flying out of Geneva. We are struggling on the best route to get from point A to point B with a lot of fun in between. Must see sites include Lucerne, the Berner Oberland, and Zermatt. We are planning on using Interlaken as a jumping off point for some fun in the mountains. We are struggling with which transportation pass to buy if any, or whether a car rental is a better way to go. And we are still trying to find the most effective route to hit all our high points. Any tips or suggestions would be so wonderful!
