My husband and I are planning a 13 day holiday with our 2 year old. Our plan right now is to fly to Barcelona, spend 3 nights, travel to Rome via the overnight Ferry with Cabin. We will stay in Rome for 4 nights, take the train to Cannes for 3 nights, then train back to Barcelona for 1 night before we head back home. I like the idea of taking the Ferry and train istead of flight hopping as we will be able to see the country side on our way around. Is this too much to do in 13 days? Will we be going crazy by the end? Thanks for the help!
