Serena Williams is offering an inside look at her family trip to Disney World!

The retired tennis legend, 43, shared a carousel of photos from her fun-filled getaway on Dec. 9 that also featured her sister and fellow tennis star Venus Williams, 44.

In the comments section, the sisters’ fans couldn’t help but point out their refreshed looks in the shots of just the two of them posing in front of the castle and at the Tron Lightcycle / Run roller coaster at Magic Kingdom.

“Ok but you ladies seem to be aging backwards,” one person commented on the post, while another added, “Wow you ladies stole the fountain of youth 40 something ain’t what it used to be.”

Others pointed out how they didn’t realize it was Venus in the photos at first.

“Venus looks like a damn teenager! Omg I didn’t even recognize her,” read one comment.

Another added, “Is Venus aging backwards… She looking like she 21 years old.”

The sisters were also joined by their mom, Oracene Price, their half-sisters, Lyndrea Price and Isha Price, and Serena’s daughter Olympia Ohanian, whom she shares with husband Alexis Ohanian.

In the shot, the group pose in front of Cinderella Castle at Magic Kingdom as Serena holds her daughter’s hand. Other snaps from the vacation show Alexis wrapping his arm around his wife as they appear to be seated for a show, as well as their half sisters posing with Olympia for a selfie.

“There’s nothing like a quick family trip to @disneyparks. There’s no place like Disney,” Serena captioned the post, followed by a smiley face emoji.

Fans first commented on Serena’s look in a Dec. 7 Instagram post that showed her shaking her hips to Bad Bunny’s song “DÁKITI.”

In the comments, one fan wrote that she “slayed” the look and was absolutely “stunning.” Another added, “Looking amazing. Time to get u back on the court.”

One comment read, “She is feeling it! Serena William is in the zone… Good for her,” while yet another fan chimed in, “She got that makeup right and looking great!!”

During an exclusive interview with PEOPLE in November, the 23-time Grand Slam champion opened up about how her fitness goals have changed as she’s planning to run a half-marathon by the end of 2025.

“That’s my new goal. So it’s just like I have to do something competitive. I miss tennis like crazy,” said Serena, who officially retired from the sport in 2022.

Serena — who also shares daughter Adira, 1, with Alexis — elaborated more on her fitness routine amid her training for the upcoming race, and explained how it compares to her old routine for tennis.

“I’ve gotten obsessed, more obsessed with diet and exercise, I think, than when I was playing tennis,” she told PEOPLE. “I knew that I was going to burn 20,000 calories a day, and now I’m like, ‘Oh my god, I don’t know how many calories I’m going to be able to burn!’”
