The Keeping Up With the Kardashians stars were spotted lounging oceanside, with Kourtney looking stunning in a white one-piece bathing suit and Scott soaking up the sun right beside her.
Kourtney and Scott appeared to kick off their trip with a date night, as the mom-of-two posted a photo of herself and Scott posing all dolled up on a balcony.
"Miami nights!," Kourtney wrote alongside the photo, in which she sported a flowy pink dress.
This is the latest trip for the couple, who headed to Las Vegas last weekend with Khloé Kardashian Odom to attend the iHeartRadio Music Festival.
