Frommer's
Oyster
Frommer's "Older kids will appreciate the teens-only game room; the water slides, lazy river, and swim-up soda bar at Pirates Island waterpark right on Seven Mile Beach; self-serve soft-serve ice cream bar; and the Xbox lounge"
Oyster "The location, right on Negril’s Seven Mile Beach, puts the resort a short drive away from the town center and a number of shops, boutiques, and craft markets, as well as restaurants and bars"
