My wife and I did the 11AM walking tour with Jack today and enjoyed it very much. A someone previously mentioned, you do not get to fully explore the sites you are visiting. Luckily, my wife and I did this tour after seeing much of Krakow on our own. This tour was an excellent supplement to our own exploration.
While my wife and I did not make any new friends (shy Canadians?) we did notice that many people were introducing themselves to one another. I think it was a great opportunity for people traveling on their own to meet new people!
