Surrounded by 160 friends and family, Benitez and DiDario exchanged self-written vows before sunset at the historic Walton House, a secluded English cottage framed by tropical gardens.
"It's so special to see how excited our friends and family have been about this wedding," says Benitez, 30. "It truly is a celebration of love – our own, and what love means in their own lives. We are so moved and humbled to celebrate together."
Adds DiDario, 30, whose sister Megs officiated the wedding: "The support and love our family and friends have shown throughout this journey have made the entire experience that much more special."
Both grooms wore J.Crew tuxes and custom-made ties by David Fin for their big day, with Benitez opting for a midnight navy combination and DiDario donning a chambray charcoal ensemble.
After their first kiss as husbands, the duo got the party started with their first dance to Il Volo's cover of "Can You Feel the Love Tonight" from Disney's The Lion King.
The couple was feted by many members of Benitez's extended news family, including Sam Champion, Shepard Smith, Martha Raddatz and Kevin Ozebek, Benitez's best man. Desperate Housewives creator Marc Cherry, publicist Howard Bragman and Broadway director and producer Richard Jay-Alexander were also in attendance.
Prior to the celebration, the couple had a pre-wedding getaway to Key Largo, Florida, with family and friends.
Benitez popped the big question to DiDario in front of the Eiffel Tower in Paris in September, with photos of the romantic proposal trending on Facebook.
Speaking to PEOPLE of their chance meeting on Instagram, Benitez said, "I used to be one of those guys who never really thought about marriage, and then I met Tommy."
