I just completed arrangements to visit Venice for a couple of days later in August, on the back end of my week at Oxford. The program had an optional extension to Paris, which I bagged because it seemed overpriced, so my return flight was scheduled four days after we finish up the program in Merton College. So now I'll have a night in Zurich (my first time in Switzerland, strangely enough), two in Venice, and another night in London.
