Which part if Sentosa will you be near? Activities such as a stroll, playing at the beach, swimming, mainly outdoor activities. Check out Port Belly restaurant at Palawan Beach Walk. Have fun!
Kidzania! I haven't been there but heard good things. Take a swim in the beach. Watch the merlion show at night. See Wings of time show.
