luxembourg - 1981
Went there as a kid and don't really remember very much about except a really large red bridge, which, after a minute's surfing on Google apprently is the "Grande-Duchesse Charlotte bridge, also called "Rout Bréck" (red bridge)".
Google is omniscient.
I also remember staying at a Holiday Inn (!) which turned out to be a 5-star hotel with a gourmet restaurant on the ground floor. One night we had dinner with Yehudi Menuhin at the table beside us. At that point he was at the height of his popularity just having hosted the TV series The Music of Man.
Unfortunately no photos of the trip that I can find.
