It should come to no surprise that the city's hottest tourist destination makes it to the list. Not only can you marvel the impressive structure of the 57-storeyed Marina Bay Sands, but you can head up to the boat-shaped SkyPark for a bird's-eye view of the city. You can also check out the infinity pool, but no dipping please, that's for hotel guests only.
While you're there, indulge in some retail therapy at designer boutiques like Chanel, Fendi, Gucci, Yves Saint Laurent and more occupying The Shoppes at Marina. When you're feeling peckish, stop by one of its many celebrity-chef restaurants for the A-List treatment.
Not looking to splurge? Book front-row seats to the latest musical gracing the stage of Sands Theatre or step through the doors of the lotus-shaped ArtScience Museum for immersive art, science, culture and technology exhibitions.
For a change of scenery, smell the roses at Gardens by the Bay or lay out the mat for a romantic picnic at Marina Barrage. And don't forget that mandatory selfie with the Merlion by the Fullerton Bay Hotel Singapore.
