The 32-year-old and Kourtney, 36, ended their relationship last week, after he was seen with his rumoured ex-girlfriend in St. Tropez.
While Kourtney is struggling to keep it together for the sake of their three young children, Scott took to Instagram to share a picture of his current location.
Alongside the snap, he wrote: "Goodnight with a dream bedroom."
But his followers were quick to criticise his insensitiveness. One fumed: "Are you seriously posting about how fabulous your suite is? Get a grip, face what's real. You're pathetic & superficial [sic]."
Another said: "Your children must feel similar like you did when you lost your parents… with the little difference that you had the choice to leave your children."
They were referring to the death of both of Scott's parents – his mother passed away in October 2013 and his father died just three months later.
It's the second time this week Scott's followers have ordered him to act up. His daughter Penelope turned three on Thursday and, instead of going home to be with her, he posted an Instagram message.
