It was my impression that there was no need to prepurchase this ticket (Varenna-Manarola). Today, I decided that since travel was on a Sunday and I could save about 10 euro per tix by advance purchase, that I would go ahead. There is a route thru Milan that typically takes 4.5 hours. I tried both Loco2 and Trenitalia and they are not finding that particular route, just routes that take almost 7 hours. So then I thought, I will just buy Varenna to Milan and figure the rest out later. At that point I realized that it is the second leg out of Milan that seems to be sold out???? I'm thinking maybe by playing around with CT destinations I could figure something out, but is there someone that has a quick answer to this? I only have two nights in Varenna and two in Manarola and this issue may cause me to change our plans.
EDITED TO ADD: Is this possibly/hopefully one of these situations where they haven't posted the tickets yet?
