Hi Laurie, I have heard other news about the Festival. It seems that this year it is gonna be a very special year because also the statue of St. Peter venerated in the near town of Maiori will come to Amalfi and carried in procession along with St. Andrew (in fact according to the Gospels, Andrew and Peter were brothers and for the Catholics this year is the Year of the Faith so this is a very special way to celebrate the occasion).
Anyway, the statue of St. Peter will leave Maiori's port around 4.30 pm and will arrive in Amalfi around 5.00 pm. For the rest the schedule is the same I told you before.
I hope you'll find this information useful. =)
