We are 4 couples in their sixties [ages 62 - 69] intending to arrive June 27 and leave July 2. We cannot arrive before June 27 and we need to fly to Montreal July 2 so our time is unfortunately limited. We can handle light walks and are interested in history, culture, scenery and food. Have planned nothing yet - we are prepared to do a guided tour as well, but we're not sure if we have enough time. Would welcome advice / suggestions. Thank you.
