Stay: Quarzo Bal Harbour
Space is the draw at this recently opened property near the exclusive Bal Harbour Shops. (Look for Gucci, Prada, and Bottega Veneta, plus the excellent Books & Books.)

Great Value Rita Hayworth and Gregory Peck are among the stars who once stayed at this revamped 1920 compound, another product of Henry Flagler's bold vision. Doubles from $199.
See: Key West Sunset
The main event in town. You could brave the carnival-like Mallory Square, where the rowdy Sunset Celebration involves sword swallowers and fortune-tellers. Or you could sit back with a cocktail at Casa Marina's Sun Sun beach bar and toast the day's end in a more civilized fashion.
Dinner: Pepe's Café
Atmospheric little shack that's the oldest restaurant (est. 1909) in Key West. Head here primarily for the Key lime pie—pleasingly tart, garnished with whipped cream, and served in a bowl. 806 Caroline St., Key West; 305/294-7192; pie for two $8.

Wynwood Walls: It's part free outdoor gallery, part Disney World for grown-ups at this open-air art park next to Wynwood Kitchen & Bar. —Eleni N. Gage
