What information are you not finding? Local transportation is free. There are trains from Paris, Belgium, and Germany.

I remember going to the American WWII cemetery where Gen George Patton was buried.

It is a nice city and if you have time try to visit Vianden, Lux. on the German border.

We enjoyed some time in Luxembourg tracing my husband’s family a few years ago. It’s a beautiful, peaceful little country … we stayed in Diekirch but wished we had stayed in Ettelbruck, which is a transportation hub … if you’re taking advantage of the free buses and trains, you’ll likely make changes here.

We enjoyed the amazing, huge WWII museum in Diekirch; the castle at Vianden; the Family of Man photographs in Clervaux. Never even made it to Lux City.

The towns we visited had french fries as good as Belgium, gelato worthy of Italy, and some great little restaurants. Here’s a link to a forum discussion which may give you more info.

Opinions on what are must see and must do's. Recommendations on restaurants.

Did you check the links? I used the info in the links for trip planning. The link to the tourist office has all kinds of information.

There are lots of recommendations on these blogs.

I was there last week on a day trip from Metz, France I signed up for a free walking tour that was very informative and for me I felt the one day there and wandering around Luxembourg City after my tour was sufficient.

Been there, no need to return. The central park (sort of a ring), which used to be the Prince's hunting grounds if memory serves, is rather fetching, and the WWII museum is interesting, but otherwise not much is extraordinary compared to what you experience elsewhere in Europe (architecture, food, street scene, etc.). One little tidbit, don't touch the merchandise when shopping! This is a general rule in Europe, but the one place I really got yelled at was when I touched the fabric of a shirt I was considering in a shop in Luxembourg. I don't know if they're any better or worse than other cultures when it comes to the no-touch rule, but I wouldn't chance it again in that country.
