Beaches Turks & Caicos and Hyatt Ziva Cap Cana are the moves here—both are engineered specifically for mixed-age families, with enough infrastructure (water parks, character meet-and-greets, dedicated kids clubs) that parents actually get downtime. If you're choosing between all-inclusive versus resort-only, Beaches leans harder into the "we'll entertain your kids aggressively" camp; Cap Cana trades some of that pizzazz for a quieter enclave feel. The Bahamas and Aruba picks are solid if you prefer a traditional resort setup with pools and beach access, but they're gentler on the kids-programming front. Beaches Negril works if budget tightens—same Sesame Street DNA, different island.
