Cynthia – thank you very very much for your detailed reply! Bummed I just left Luxembourg – would have been awesome to have met up. My sister and I were there this time – we met with one of our relatives and primarily hung around the city hopping from cafe to cafe trying to get all our eating and drinking done before 7pm! I have been to Vianden before – wasn’t to crowded when I was there; I will definitely keep your other recommendations for my next trip, and there will be more trips to Luxembourg!
