Marina Bay Sands would be a great choice as suggested by Claus. Hotel Ritz Carlton Millenia is another to consider. Located in Marina Bay by Singapore Flyer and Esplanade, this 5-star hotel is home to over 4,000 art collection and rooms with views of the city. For the ultimate, I would combine a stay in Singapore with one of the smaller islands (Indonesian islands) close to Singapore. One that came to mind is Batam Island , only a 45-minute ferry ride away. Choose Montigo Resorts for your stay in Batam. This secluded resort offers water sports, fishing trips, mangrove tours, ATV tours, biking, and trekking trips.
