At 14 and 16, your kids are old enough to actually enjoy a real beach and water sports—not just character meet-and-greets. Beaches Turks & Caicos and Hyatt Ziva Cap Cana both nail that sweet spot: serious Caribbean scenery (Grace Bay and private beach clubs) paired with teen clubs that'll actually keep them occupied without feeling babyish. If budget's tight, Beaches Negril delivers nearly identical Sesame Street family DNA at real savings. The Cancun properties are solid too, but they're bigger, busier, and feel more spray-and-pray resort than curated family experience.
