Why you should go: Quieter and more laid-back than other popular destinations in Southern Thailand, Khao Lak offers secluded beaches, waterfall hikes and night markets. You could easily spend a week relaxing on its miles and miles of peaceful tropical shore. But if you want to add in some exploration, it's a fantastic home base for day-tripping to Phuket, Phang Nga Bay and the Surin and Similan islands.

Members only: Two people can indulge in a 5-star weeklong getaway at Kalima Resort and Villas Khao Lak for $399. (That's over 40% off publicly available rates.) Your membership also gets you perks like daily breakfast, a three-course dinner, 60-minute Thai massages and more.
