Hilton Garden Inn lays in swank retreat XVI stories up. “Versailles in the Sky” gets decadent a la Louis the XVI, with château-chic armchairs, tripped-out candelabras groping toward the open sky. Glass-roofed lounge prime for ill-weather chilling. Small plates keep with the luxury theme: foie gras, fancy cheeses, caviar panini. JBird crew on the ’tails hooking you up with pineapple juleps and Rangoon gimlets.
