Tom Brady and Gisele Bündchen continued their low-key Costa Rican weekend wedding celebration by hitting the beach and enjoying a barbecue before their big day Saturday.
The couple – along with Brady’s son John (with former girlfriend Bridget Moynahan) and his parents – hit the beach Friday around noon, where the New England Patriots quarterback chased his 1 ½-year-old son around the surf.
Brady, 31, and Bündchen, 28, relaxed by the beach with many of their guests, who later spent the afternoon lounging poolside at their hotels.
To help their guests get around the village and beaches of Santa Teresa, the couple rented seven quadcars – small four-wheeled motorcycle-like vehicles, a source tells PEOPLE.
Later, friends and family gathered at the couple s home in the area for an evening barbecue.
The night before, the Brady-Bündchen wedding party enjoyed a laidback rehearsal dinner at the Milarepa beachfront hotel.
