Thanks for the fantastic pictures. A pity that your hotel was bad. Hopefully you had the chance to get to the near "Rathaus Brauerei" (Brewery at "Altes Luzerner Rathaus"). My Uncle and I had some really tasty beers there in 2014. Funny thing is, we also had a trip to the Mt. Pilatus and the Rigi and took the boot back to Luzern.
