The Royal Hideaway is a member of exclusive hospitality consortium Leading Hotels of the World, and as such is one of the most luxurious properties in the area. It features upscale rooms with high-end amenities, a full-service spa with great treatments, several pools, and the best food around. The beautiful grounds, overall sophisticated vibe, adults-only policy, and beautiful beachfront location a short drive from shopping on Playa’s Fifth Avenue make it one of the most attractive options for couples in Playacar.

Rosewood Mayakoba is a gorgeous, peaceful retreat within the resort community of Playa Del Carmen, set on a mile-long stretch of beach. Though it features an extensive children's program, the resort largely attracts couples with its serene atmosphere, upscale restaurants, and spa. The 128 suites feature attractive contemporary decor -- picture clean lines, white walls, and rich woods -- as well as high-tech amenities and private outdoor plunge pools. They have an open-air vibe, with many floor-to-ceiling windows, and the overwater lagoon suites have swim-up access. Plus, suites include freebies such as Wi-Fi, fresh fruit, and bottled water. Seaweed debris along the beach keeps the Rosewood from being flawless (although they diligently attempt to keep it clean by sending staffers to rake it away), but otherwise this hotel is top-notch -- for guests willing to pay top dollar.

As one might expect from the ultra-luxurious Banyan Tree brand, the Banyan Tree Mayakoba is one of Playa del Carmen's most sought after resorts. All of the 164 villas feature sleek Asian-inspired decor and Mexican textiles -- as well as walk-in showers, plunge pools, walled-in grass lawns, patios with hammocks, outdoor bathtubs, and fully stocked bars. The grounds,white-sand beach, and lagoon-like pool blend seamlessly with the surrounding nature. When you consider the high-end spa, plethora of outdoor activities -- such as golf, snorkeling, and eco tours -- and the fantastic dining, it's very hard to find anything wrong with this property.

This adults-only, luxury all-inclusive property with 507 rooms appeals to both 20- and 30-something couples. A particular draw of this resort is its proximity to the nightlife of downtown Playa del Carmen, especially bustling 5th Avenue, with the party-oriented will appreciate. But the gorgeous stretch of beach and the sophisticated rooms with two-person jetted tubs means romantic-minded couples will be pleased here as well. The range of features is, unsurprisingly, extensive, including seven restaurants and seven bars, an Olympic-sized pool, a wedding center, a spa, and daily entertainment.

Paradisus Playa Del Carmen La Perla is one of the best adults-only, all-inclusive luxury resorts in Maya Riviera. This chic property is located directly on the Caribbean, but the patch of white sand is narrow and it's a bit far from downtown Playa Del Carmen. No kids allowed means the gorgeous swimming pools remain calm and serene; there's a swim-up bar and waiter service, but guests tend to be seeking peace and quiet rather than a rowdy party scene. Even the most affordable rooms have marble floors and free minibars stocked daily. An upgrade means access to a semi-private swim-up pool and/or butler service. A huge variety of all-inclusive restaurants and bars get high marks for quality and service. The spa is romantic, with a water ritual, sexy day beds, and an expansive treatment menu.

Located on the Riviera Maya, south of Cancun, the 412-room Secrets Maroma Beach Riviera Cancun is a romantic, adults-only all-inclusive resort, set on a private white-sand beach lined with sunbeds, cabanas, and palapas. In addition to the buffet, a wide range of high-quality dining options are available, including Japanese teppanyaki, French cuisine, a wine cellar with over 200 different vintages, and, for an extra charge, romantic dinners for two on the beach. A stunning destination-style spa offers couples' treatments in private outdoor cabanas on the beach. Rooms are large and tasteful, with four-poster canopy beds, separate sitting areas, and private balconies; ground floor rooms are swim-up suites. The hotel is especially popular for honeymoons and destination weddings, though numerous additional fees can make a stay here pricey.

The former estate of an Italian duchess, the ultra-luxurious Esencia oozes Mediterranean elegance and style. With just 29 rooms spread over 50 acres, the property feels intimate and exclusive, and shows a thorough attention to detail in everything from the services to the decor. Upscale, contemporary rooms are housed in two-story buildings set amid lush tropical grounds, and feature lots of high-end amenities, including pre-loaded iPods, Molton Brown toiletries, and in some, even private plunge pools. The gorgeous spa, excellent restaurant, and relaxing pools with ocean views are highlights.

Blue Diamond Riviera Maya by BlueBay is an excellent option for couples looking for a more intimate and luxurious all-inclusive option outside of the hustle of Cancun. The four-and-a-half pearl property is spread out over gorgeous grounds that are partially manicured and artistic and partially jungle-like and wild so the overall ambiance is natural and feels almost isolated. No kids allowed means the two swimming pools, sandy beach, and plethora of restaurants are generally quiet and relaxing. Adult-friendly facilities include a sleek spa (free access to use the steam room and pool), cigar lounge, and one of the best equippedgyms in Mexico. Suites and casitas come standard with private outdoor bathtubs and minibars stocked with free drinks.

The Viceroy Riviera Maya is a seriously upscale resort nestled in a lush rainforest setting 15 minutes' drive from the Playa del Carmen town center. Chic, rustic villas are awash with deluxe touches, and private patios feature heated plunge pools and alfresco "moon showers." Although rocky in places, the beach has white-powder sand and turquoise waters; it makes an attractive backdrop to the serene pool area and sea-facing restaurants. While families with kids should look elsewhere (children under 14 are not allowed) couples looking for a secluded, romantic retreat -- who aren't afraid of splashing the cash -- will be sure to find it here.

The 310-room, luxury, all-inclusive Iberostar Grand Hotel Paraiso is a Las Vegas-style, adult-only resort on the Riviera Maya. The resort is part of the five-hotel Iberostar complex, and guests at this hotel may use the amenities at all five properties, some of which are family-friendly. The high-end experience starts with champagne upon arrival, and continues with premium liquor, fine dining, a full-service spa, and several pools, including one dedicated to tranquil relaxation. The opulent decor incorporates marble and mosaic floors, glass chandeliers, modern artwork, and artisan-crafted furnishings. The lush, landscaped grounds complete the picture. Rooms are large and upscale, with jetted tubs, glass shower stalls, and personalized minibars.

El Dorado Maroma, is an adults-only all-inclusive about 40 minutes south of Cancun. The resort is smaller and quieter than many nearby all-inclusives, but it’s chock-full of amenities. There are six on-site restaurants, numerous bars, multiple pools, aspa with beachfront massage services, and a modern fitness center. There is a wide range of room options at El Dorado Maroma, including suites with swim-up terraces. However, the beach -- which is little more than a marina with sand -- is disappointing. Food and drinks throughout the hotel are fairly mediocre, but most restaurants feel character-less and slightly unappealing. And despite being an all-inclusive resort, the hotel charges an extra fee for Wi-Fi.

Right off the beach in a secluded area 15 minutes north of Playa del Carmen’s center, the 23-room Le Reve Hotel & Spa has an instantly relaxing vibe well-suited to couples and honeymooners. The boutique hotel's interiors are upscale and stylish after a 2014 makeover. Rooms have lots of special elements ranging from hand-painted tiles to plunge pools, though dim lighting can be a downside -- as can the price of cabs to and from Playa proper. However, positive features include the (unsupervised) kid’s club, pool bar, massage area, classy sports bar, and impressive gourmet restaurant menu.
