A weekend in South Beach ought not to begin with “What to pack?” but rather, “What to pursue?” Do you long for the South Beach of painted-on dresses, frozen margaritas and electric neon? The South Beach of stylish new (or renovated) hotels (Gale, Lord Balfour, SLS South Beach) and restaurants (Yardbird Southern Table & Bar, Khong River House, Tongue & Cheek)? Or the South Beach of yesteryear, of pastel Art Deco buildings, museums and monuments? Perhaps you simply crave …the beach. Miami can be whatever you want it to be — laid back, decked out, gay, straight, a family recess, a single’s playground — which is precisely what makes it such an effortless getaway. In this dreamland at the southern tip of Miami Beach, you can choose your own adventure.
