Singapore is a destination where you don't really need too many days to explore the whole city-state. Once you've exhausted the city, or just want a change of pace, a day trip to Sentosa Island is a great option.
Sentosa Island is known for housing Resorts World, Universal Studios, pristine man-made beaches, and golf courses. It's so easy to get there by cable car, MRT, or just to simply walk across the Boardwalk.
Once you're there, you can walk around the island or talk the free shuttle buses going around the island making stops along the various beaches.
For a getaway and a fun day to play, Sentosa Island definitely is the place to take in the sun or hide away in the casinos.
