Should I make reservations/get tickets in advance for travel from Rome to Murren? From what I understand, we'll have to go from Rome to Milan. I found ticket info on http://www.sbb.ch/en/home.html but I'm not sure if we should make reservations before we get to Rome. We arrive Rome on July 8, and are hoping to depart for Murren on July 13. Any tips would be greatly appreciated!
