Hello we are planning to travel to Europe with our Three children , 10, 12 and 1. We would like to do the highlight cities, mainly Paris, Amsterdam, Rome, Venic and Florence. I was planning to book a flight into Paris and out of Rome when returning. Could someone give me an idea of this possiblity in 13 days?. We are planning to train, fly or rent a car. Whichever works best.
