>> Giving the difficult technicalities of travelling is Switzerland, I find it a bit doubtful to do all these sites as daytrips from Luzern. I've been to Monte San Giorgio myself, that's already quite a trek from Lugano (itself 2 hours away from Luzern by car). If you've experienced otherwise, I gladly hear so.
I did use Zurich (quite near to Lucern) as a hub for day trip to Bellinzona, St. Gallen and Richenau. All of these trips required a very well plan schedule with load of help from sbb website.
