LGBTQI+ scene
Miami concentrates its LGBTQI+ scene in South Beach (SoBe) — an "LGBT lifestyle hub", according to Wikipedia. Ocean Drive (5th to 15th) and Washington Avenue are the nightlife axes; Lincoln Road is the daytime gay-friendly pedestrian street. Iconic venues: Twist (open since 1993, a multi-storey complex open 365 days a year) and Palace Bar (drag brunch on Ocean Drive).
The second pole is Wilton Manors (Fort Lauderdale metro area, 30 min to the north) — Wikipedia notes that it has one of the highest concentrations of same-sex couples in the US, second only to Provincetown, with Wilton Drive as its axis. Wynwood adds alternative queer and galleries. The peak season is winter (Nov-Apr) — Caribbean weather plus the escape from the cold of the northern US draws the circuit crowd to Miami.
