My husband and I along with our kids ages 13 and 8 are flying in to Rome at noon on Thursday May 30th flying back at 7:00 am on Wed June 5th. This gives us half a day on Thursday May 30th when we get there and 5 full days before flying out at 7:00 am on Wed June 5th. We definitley want to see Rome and Venice add Florence if we have time! Looking for itenirary recommendations for the 5 and a half days. Would train be the best way to go from Rome to Veince? Can we add Florence and able to see all 3 places or is that too much?
