But the couple made it more of a family affair by bringing along the KUWTK star's three children, sons Mason, 11, Reign, six and daughter Penelope, nine.
Giving fans a glimpse at the getaway, Scott shared a snap of himself and Amelia sharing a sweet moment with Reign by the water.
'Great night just a little smelly for reign out on these old docks,' Disick wrote on the inside of the image, which explains why Reign was holding his nose shut with his left hand.
In the photo, Disick was dressed in camouflage sweatpants and a white t-shirt.
He also donned a pair of white and blue Nike sneakers and had his short cropped hair still dyed platinum blonde and shaved ultra stubbly on the sides.
Disick, 38, also shared a photo of his daughter Penelope sitting on top of a Mercedes SUV, which is likely the rental car he's using while visiting The Hamptons .
The nine-year-old looked adorable checking out her phone, while dressed in pink sweatpants, a matching sweatshirt, and slip-on shoes.
Three days earlier, Hamlin, 20, teased her 985,000 Instagram fans and followers by sharing a series of snaps of herself while out getting ice cream with Disick.
Some of the shots showed Amelia taking some licks of her tasty sweet treat, while another showed the couple seemingly walking away from the ice cream shoppe, with their backs to the camera.
'They had some friends over a couple of nights, hosted a few dinners and pool days with the kids,' a source said of their time in The Hamptons, according to Fox News.
That insider said Disick took his lady and their kids out of a rented boat for a relaxing day out on the ocean.
Cosmopolitan magazine is reporting that the couple are planning on living at the rented home for the entire summer.
Scott and Amelia are reportedly using their time with the children as an opportunity for everyone to get to know each other even better.
'She's learning a lot, it's definitely a whole new world for her, but she loves being around them and is grateful she gets to have this experience,' an insider said of Hamlin.
'She thinks they are amazing and is really good with them. Her and Scott love planning fun activities with them.'
Scott shares all three children with ex partner Kourtney Kardashian, who he spit from in 2015 after over a decade together.
Back on July 8, when Penelope turned nine, Hamlin took to one of Disick's Instagram photos to share a happy birthday message to her 'little peesh.'
"Happy birthday to the best facialist in town," Hamlin wrote in the caption along with a pink heart emoji.
The proud father celebrate her birthday, with the caption: 'My life my love my everything. You have changed my life forever Peep. I love you too much!!!!!! And will never stop loving you each and every day for the rest of your life and will protect you till the day I die. HAPPY BIRTHDAY PENELOPE.'
The couple, who have been criticized for the 18-year gap between them, have been dating since November 2020.
