We'll be in Genoa while on a cruise and plan to take the train to Portofino. I see that the regional train is cheaper than the intercity and ~20 min slower. Thinking of taking the regional to save money (it adds up for 5 people), but wondering if I'll regret it. Would a Sunday in mid-June be crowded on the regional train (to Portofino around 9-9:30 am, train back around 3 pm)? Do intercity trains have a/c, while regional do not?
Thanks!
