Welcome to Switzerland! I hope you are still able to read this message.
I would definitely go on a extended boat tour in Lucerne:
If you are in Vitznau, please take your time enjoy the beautiful lake view and have a bite to eat at any of the lake front restaurants.
When you return to Lucerne main train station, please stop by at Läderach chocolates (which is one floor down) and buy some Swiss, artisan chocolates there for you to enjoy and wind down.
I wish you a safe flight back home!
