Looking forward to our Sept 2024 trip. I am wondering if anyone has recommendations for the free time listed on the itinerary. Day 2 in Gruyeres, Day 3 after the Matterhorn Museum, Day 5 in Lugano free afternoon and evening, Day 8 in Interlaken, and Day 10 in Lucerne. I appreciate any suggestions or tips to make our trip even better than I expect.
