The Outpost Hotel Sentosa
Time Out says
This new upscale property in Sentosa exclusively caters to adults, so you won't be rudely interrupted during your romantic pool date by the sounds of wailing children. Stay in one of the 193 stylish guest rooms with chic design inspired by Singapore's distinctive colonial black and white bungalows. For a sundowner, head up to the lush rooftop overlooking the sea. Take a dip in the pool exclusively for guests while ordering your favourite cocktails from the bar.
