Greetings,
I'm looking to travel from Rome to Bolzano next month (mid June) by train. We are a group of 4 people (2 adults and 2 teenagers). This is the first time my family and I are traveling to Italy from California. I'm seeing frequent train routes offered by Rail Europe: https://www.raileurope.com/en-us/destinations/trains-to-bolzano.
I'm wondering from more experienced travelers if I should book in advance - do the train routes sell out in the busy summer months? I would appreciate any advice you might have if you've traveled this route, or other possible train/transportation option to consider?
Thank you -luisa
