I don't know, Alan.
No matter what Orson Welles might have said on the subject, you might want to consider that in the years just after World War II, tourism was not the pre-packaged experience it has become now. After all, in the early 1930's, did not Welles travel in Ireland, Spain, and Morocco itself, where he claimed to have stayed in the Sultan's castle? That nobleman or perhaps his son was such a great fan of Welles that he began to name squares and monuments after him. Then, too, a few years later, what were Welles' TV ventures in Spain, in Italy, in Austria, among London's Chelsea Pensioners, but early examples of the kind of travel program which now takes up a good amount of space on American Public Television?
Orson Welles may have looked down on "tourism," but he appears to have been "the eternal tourist" much of his life -- and many of his works show that.
