The trio was also joined by costar Miriam Flynn at the convention in Edison, New Jersey, in honor of their 1989 holiday classic
It's a Griswold family reunion!
Taking place Friday through Sunday at the New Jersey Expo Center, the convention is best known for its roster of Christmas-movie stars, which now includes Saturday Night Live alum Chase, 80, plus D'Angelo, 72, Flynn, 71, and Quaid, 73.
The foursome starred in the comedy classic in which Chase plays patriarch Clark Griswold, who faces a series of unlucky happenstances while trying to host a traditional Christmas with his family that includes wife Ellen (D'Angelo), daughter Audrey (Lewis, 50), son Rusty (Johnny Galecki) and extended relatives like Ellen's cousin Catherine (Flynn) and her husband Eddie (Quaid).
At the convention, the actor was also joined by his daughter Emily Chase and her boyfriend Alex Baglieri. "So happy to have my daughter @em_chases and @alex.baglieri come by and say "hi" at @thats4ent this weekend,” he wrote alongside a photo of them smiling in his festive meet and greet area at the event.
Emily, 35, added in the comments section, “We love you so much and had the best time!!! 🥰.”
Last year’s convention included appearances by several Hallmark, Lifetime and GAF holiday stars, including Andrew Walker, Nikki DeLoach, Paul Campbell, Danica McKellar and Autumn Reeser. They joined Mean Girls costars Lacey Chabert and Jonathan Bennett.
Chabert, 41, Bennett, 42, and DeLoach, 44, also took a snap with Chase and the stars of National Lampoon's Christmas Vacation, along with Wes Brown, Alicia Witt, Erin Cahill, Steve Lund and Cindy Busby.
Chase's appearance at Christmas Con comes days after he took a tumble at Shea's Performing Arts Center in Buffalo, New York, ahead of a talk about Christmas Vacation.
A rep for the actor and comedian told PEOPLE, "He took a fall at the part of the stage that was not lit well but thanks to all his falls on SNL, it was like riding a bike again. Just a little boo-boo. All good."

In video footage shared by TMZ, Chase could be seen emerging onstage in a wheelchair to applause from the crowd, but soon got up onto his feet. He then walked to the front edge of the stage where, shortly after, he fell forward and off the stage. After he was helped back up onto the stage, his wife Jayni Chase assisted him to his seat for the conversation.
"Wait wait, my watch is talking to me," Chase told the moderator after taking his seat, going on to joke, "It says, 'I see you've taken a great fall! ... Taken a hard fall.' "
After Jayni helped her husband reconfigure his watch, she joked into her own microphone with a laugh, "Otherwise they might send an ambulance."
