"JW Marriott Khao Lak Resort & Spa, located along the Andaman Sea, offers a swimmable 1½-mile-long lagoon, a play zone with waterslides, and a wave pool. It features a nursery for native bamboo sharks where kids can learn about the species and help release the babies into the wild. A unique experience includes a boat check-in where guests in pool-access rooms are rowed directly to their front terrace. Doubles from $358." - Marya Saidi, Shea Stanley
