Hi pinky2! how long will you be in sg? First time here?
Yea sentosa is a must go! you can spend a day at USS and another on Sentosa's attractions. Sentosa will be a great place to get to know sg and take a good look at the scenery from one of the attractions, the sky tower! You can get the Sentosa play pass and visit the sentosa attractions at a cheaper price! You can check it out from this website, newbielink:http://www.sentosa.com.sg/en/whats-on/promotions/sentosa-play-pass/ [nonactive] or when u are at the sentosa ticketing booth, u can ask about it! (: Have a good time in Singapore.
