Sanctuary Cap Cana, A Luxury Collection Resort, Dominican Republic, Adult All-inclusive

Marriott's adults-only Luxury Collection entry in Cap Cana, and the cleanest brand-stamped adults-only book in the cluster. Sanctuary is strict 18+, the room product runs to the Luxury Collection standard rather than the Marriott-default standard, and the property layout uses the Cap Cana beach more effectively than several of its higher-rated neighbors. The score (91.3) is solid without being top-tier.

The Marriott loyalty layer is the asterisk. Sanctuary participates in Bonvoy in a way the AMResorts and Hyatt properties in the same cluster don't — points-earning, status recognition, suite upgrades when available — which materially changes the math for travelers with meaningful Marriott engagement. At $4,788 a week, it undercuts Secrets Cap Cana by a real margin and Zilara by a larger one.

What you're paying for: a Cap Cana adults-only week with a Marriott brand stamp and a Bonvoy-aware pricing structure, at a number that punches above the score implies. The trade-off is that the score isn't elite for the cluster — Zilara and Secrets both rate higher. For Marriott loyalists who want Cap Cana, Sanctuary is the obvious book; for everyone else, the Hyatt and AMResorts options give back more on the food and the room.
