Hi Margarita, I am also booked on this tour and am looking for a roommate. I am a retired professor and University Administrator and get along with a wide range of people. I am an experienced traveller and will be leaving from Philadelphia on November 5 and returning to the US on Novermber 23. I would be very much interested if we could engage in a dialog to see if we would likely be compatible roommates. Please contact me through the system email or just a response to this message and we can find a way to talk.
