 "No worry, cuz you’ll be chillin with the under 30 crowd in the action-packed lobby bar, excellent Josephine Estelle restaurant; packed rooftop pool and bar Alto; 3 Keys club space; and Seaworthy oyster bar" 
 "It’s far enough away from the madness of Bourbon Street, but still only a languid stroll to bars and restaurants" 
 "Perched atop the Ace Hotel, this poolside lounge offers Italian-inspired salads, small plates and skewered meats from the chefs of downstairs hot spot Josephine Estelle, plus seasonal cocktails, craft beer & wine all in a gardenlike setting with views of the city" 
 "YOU SHOULD KNOW Ace isn’t for everyone: depending on the event, some nights the lobby can transform into a clubby lounge or rock show, and though it’s welcoming of everyone, the ultra-hip and fashionable crowd (including the staff) can be intimidating for some" 
 "Eating, drinking, and music are a big deal here, with a concert venue and multiple restaurants/bars including a wildly popular rooftop bar and outdoor pool"
