Fodor's "Highlights here include the tropical gardens, which are protected from the fierce northeast winds (difficult on this side of the island) and are filled with 260 different palms, and four pools that are big enough to accommodate all guests"
Oyster "The hotel caters to families and couples with several pools, decent dining options, a full entertainment program for all ages, a spa, and a gym"
The Telegraph "The outdoor spaces have the biggest appeal: there's a sprawling split-level swimming pool, stretch of beach, tropical gardens, and rooftop that's all palm trees and volcanic-rock walls"
