There is a difference between a mileage run and a vacation. Your original itinerary is a pure mileage run. The itinerary in post 8 makes much more sense. 3 days is an absolute minimum in most European cities. Otherwise why bother going? You can be tired and stressed at home..... One tip leave plenty of time for sleep on day 1. Flying TATL East is pretty brutal on the biological clock. Otherwise you will be exhausted and sleep deprived the entire trip.
