Been traveling and am towards the end of my Switzerland trip. So far I’ve been 4 full days in Wengen and 1 full day in Zermatt and saw the Matterhorn! Tomorrow I can take a late 6:45 pm flight (or a redeye the next day) to my next destination (Istanbul) where I have 3 nights in total. If I did that I could spend the day in Luzern. Is Lucerne a must see in your eyes? Or should I save it for another trip to Switzerland?
If I saved Luzern for later I could take a 7 am flight to Istanbul. That way I have about a half day more in Istanbul.
