The Villa, formerly known as Miami Beach's Versace Mansion, is open to the public as a wedding venue. The luxury hotel keeps events limited to a number of calendar days and weekends. The price tag for a few hours will cost you upwards of $13,000. That's just to rent the space; it doesn't include all the other details that make for a complete wedding.
Still interested? My advice is to partner with an event planner and let them secure the site for you.
