We have our tickets to London (the cheapest transatlantic fare) and now we're reconsidering, and wondering what would be best itinerary be with a 16 year old boy and 13 year od girl. Originally, we wanted to go to Barcelona for 1 week and Italy for 1 week, but now we are flying to London, because it saves us almost half the price (2800Cnd) for 4. Perhaps 3-4 nights in each city and return to take our plane back in London. We don't want to do Paris, because we've done that many times. Is London, Barcelona and Italy (rome-luca-cinque Terre) still a good itinerary or something else? Your thoughts & opinions would really help and apartment recommendations in each city would be so wonderful.
