It was mostly a family affair for celebs in Turks and Caicos over the weekend.

Movie, TV and reality stars such as Jesse Eisenberg, Nicole Ari Parker, Chad Michael Murray, Dorinda Medley and other VIPs took over the Caribbean island for the opening of Sandals’ Treasure Beach Village at Beaches, where they worked out with Amanda Kloots, learned Mahjong, and gave back to islanders.

Eisenberg kicked off his trip visiting students at the Oseta Jolly Primary School. We’re told the “Now You See Me” star almost didn’t make it due to a delayed flight, but he rushed to the school immediately after he landed on Friday and hung out with male students for Boys Day.

“They were super excited to play strategy games with him, and to take photos. It was very special for the kids,” a source told Page Six.

Kelly Bensimon also made a trip to the school on Friday, where she joined the children for a reading day, we’re told. The duo were accompanied by Sandals Foundation head Heidi Clarke. It was a meaningful charitable act for the island and students, Adam Stewart, the executive chairman of Sandals Resorts International told Page Six.

“The Caribbean is our home and so caring for our neighbors, team members and local communities is at the center of everything we do,” he said. “This is why 100 percent of every dollar gifted to the Sandals Foundation goes toward meaningful action. Through programs aimed at education, community, and conservation, we’re building a better tomorrow. That’s what the Sandals Foundation is all about,” he added.

Meanwhile, back at the resort, there was a “Brown Sugar” reunion with Parker, her husband Boris Kodjoe and their co-star Taye Diggs. The trio were spotted dancing and laughing at the resort’s big finale party on Saturday night. Visitors fanned out over Parker, with several commenting on how she was their favorite on “And Just Like That…” The couple were on the island with their 21-year-old daughter, Sophie.

Reality star Medley was on the scene with her daughter, Hannah Lynch. Bryan Greenberg and Jamie Chung took the beach with their little ones, as did their pals Dave and Odessa Annabelle. Chad Michael Murray and his family celebrated his son’s 11th birthday during their stay.

Meanwhile, unbeknownst to organizers, some gummified childless influencers brought adult antics to the family fun weekend.

In fact, one caught such a serious case of the munchies that not even the scorching temps could prevent them from ordering up a feast that included hot clam chowder, steak, cheesecake, and hot fudge sundaes from the all-inclusive menu.

One was so stoned they thought they were transported to the set of “Righteous Gemstones,” they told nearby guests.

As for Mahjong? Martha Stewart’s executive director of design, Kevin Sharkey, was so impressed with the game, he vowed to bring it back to NYC to teach Stewart, we hear. Former model, Cory Bond, however, was the winner, beating the group in the game.

Other notables who helped fete the Treasures Beach Village launch included: Sam Champion, Ross Martin, stylist Tiffany Reid, “Today with Jenna & Sheinelle” executive producer Talia Parkinson, NewsNation’s Paula Froelich, Avenue’s Peter Davis, The Daily Front Row’s Eddie Roche, Melissa Roxburgh and Sean O’Pry.
