I'm about to book train tickets but am wondering how much time to allow between hotel and train station? In Venice we will be taking a water taxi and in Rome, regular taxi. Staying at the Hotel Le Isole in Venice and the Trevi Beau Boutique in Rome. I want to book tickets for early in the day but not so early that we are getting up before dawn! Knowing about how much time to allow to get to the train station will help.
Thanks!
