Siesta Key (2017 ) Siesta Key is a barrier island in the Gulf of Mexico off the coast of Sarasota, Fla. But perhaps more importantly for reality show viewers, it's the setting of this sultry series from the producers of `Laguna Beach' that follows a similar formula as that mid-2000s show. `Siesta Key' follows some young adults who confront issues of love, heartbreak, class and looming adulthood while spending the summer together in their sun-drenched hometown. Nothing is off-limits as the friends come of age and try to figure out who they are and who they want to become, which probably includes getting romantically involved with each other.
