Star Service
Oyster "Revamped in 2014, the hotel is now up to modern standards and compares to resorts like Gran Caribe -- though the Gran Caribe has a wider beach, and is farther from nightlife"
Travel + Leisure "This all-inclusive beach resort is a perfect choice for Spring Breakers who want to enjoy all the craziness of nearby Party Center while retiring to more refined, upscale accommodations"
Star Service "Both the Riu Palace Las Americas and Fiesta Americana Coral Beach provide more sophisticated environs, while the relatively puny Be Live Viva Beach provides A-I fans in this neighborhood with something more akin to a boutique hotel experience"
