Jordan in 2002 - sea, sights and excellent people. London in 2004 - museums, food, shopping, events.
But best of all was Germany last year - great weather, visited wineries, had a day in a spa, saw lots of sights and there was a great nightlife, plus it didn't cost a fortune. Stayed mainly in Marburg, visited Frankfurt, Bad Nauheim and Wiesbaden, Trier and Cologne.
