Many Dominican resorts show off photos of candlelit dinners, secluded beaches, and mesmerizing sunsets. What they won't show you are the screaming toddlers, the poolside beer-chugging contests, and the flies buzzing around the buffet. After touring the D.R. incognito, we can assure you that these hotels (many of the adult-only) truly deliver -- comfortable rooms, scenic pools, blissful spas, and a discreet yet obliging staff.
