The report said the press will be located in a hall of the enormous City Center Rosario complex where the entire wedding and reception will be held.
Messi and his wife-to-be Roccuzzo met in Rosario and have been inseparable since.
Barcelona great Lionel Messi is all set to marry his childhood sweetheart Antonella Roccuzzo in Rosario, Argentina on Friday as they host celebrities from around the world for Latin America's "wedding of the decade".
Guests at the wedding will have access to the on-site casino, a fully functioning bowling alley, grass tennis courts, an indoor and outdoor swimming pool along with a number of bars and restaurants.
Former Barcelona players who will be there include Xavi, Carles Puyol and Samuel Eto'o. With local media predicting some 600 guests to attend the event, security is high in the city.
One absentee who was given an invite but unable to make it to Argentina is captain and friend Andres Iniesta who has just become a father for the third time and will instead remain in Catalonia with his family. He also invited his neighbors from Rosario to join, which is adorable in its own way.
