Why you should go: The white-sand beaches of Central Vietnam are blissfully under the radar. Case in point: Canh Duong Beach, where turquoise waters and spectacular mountains meet. Enjoy the surrounding beauty with a 5-star stay at Angsana Lang Co. The luxurious resort features a free-form pool, four restaurants, a rooftop bar and more.

What's the big deal? Spend a week through December for just $799. (Yep, that price is for two people.) Members score bonus perks: shuttles to UNESCO World Heritage sites and a Vietnamese coffee-making class.
