JW Marriott Guanacaste Resort & Spa is a four-and-a-half pearl hotel located on Playa Mansita beach. The resort’s 310 guest rooms are subtly luxurious, offering marble bathrooms and roomy private balconies or terraces. Excellent on-site amenities include a sprawling infinity pool, an array of first-rate dining options, a swanky spa and fitness center, along with access to pretty (if tiny) Playa Mansita. The property earns top marks in all areas, but everything, from the restaurants to the minibars, is expensive. Travelers may want to compare rates and amenities with the equally fabulous Four Seasons Resort Costa Rica at Peninsula Papagayo.
