Il celebrante indipendente e' un alternativa al wedding planner?

No, the celebrant is not an alternative to a Wedding Planner. A Wedding Planner organises the wedding day from the venue, to the flowers and lunch. A celebrant works exclusively on the wedding ceremony. A couple from abroad who want to get married legally in Italy will need to work with a Wedding Planner in order to deal with the bureaucracy and all the other details.
