JW Marriott Santo Domingo In many ways, there are two Santo Domingos: the aforementioned Colonial Zone and the bustling modern Caribbean metropolis. If you’re looking to experience the latter, this is the spot: the JW Marriott, a sleekly-designed high-rise hotel set above the city’s leading luxury shopping mall. The rooms are crisply appointed, the food is outstanding and the glass-floor rooftop bar (above) is the height of Santo Domingo hip.
