I am planning the trip from Vernazza to Venice. I find it difficult to gauge how long to leave to change trains. For instance, there is a good connection from Vernazza to La Spezia, La Spezia to Firenze S.M. Novella and that goes to Venice. However, the time given to change in Florence is 23 minutes. The next train is another hour after that. Since you cannot change your tickets, is 23 mins. enough to get the connection? Maybe better to spend the one hour 23 minutes in Florence train station rather than stressing out.
Also - I presume 30 mins to change trains to Florence in La Spezia is sufficient?
There is a good connection also from Vernazzza via Monterosso, Milano Centrale to Venice but there is only 15 minutes to get the connection in Milan. Seems too tight. I understand the Milan train station is huge! I think I prefer the route via Florence.
Which trains can be reserved in advanced and which cannot be? Is it cheaper to book in advance?
Thanks for this!
