I kindly recommend to start organising your wedding in advance.
Most of the weddings from 2020 are postponed to 2021.
That doesn’t mean that there won’t be room for you but if you really want to get married in Italy on 2021, please start looking for a venue as soon as possible.
Months
If you don’t have a preferred wedding date, think about the possibility to get married April/May and October in Tuscany, Umbria, Marche and South Italy.
You will be impressed!
Midweek
Many locations I work with love to organize a midweek wedding.
