Hello...we will be leaving Vernazza on Friday, Oct. 24 and headed to Rome. We already have our Eurail passes. A reservation is required on one of the trains. How far in advance should I make the reservation? We will only be in Vernazza for a day (coming from Florence. Can I wait and make the reservation from Florence or should I make it over the internet from my home in the US? Please help. I really want this to be a perfect honeymoon!!
