Hello Kelly,
I spent last Easter in Sorrento and was able to experience two Good Friday processions. The first, the Processione del Venerdi Santo (also known as the "white procession") was at three in the morning. The other, La Processione del Cristo Morto (also known as the "black procession") was at nine in the evening. They were somewhat similar, but quite an experience. It was amazing to see hundreds of people standing along the roadside, noisy until the procession began, then it was incredibly quiet and reverent. It was so interesting to watch this very old tradition. Hope you can find someplace you'll enjoy as much.
