Hello Laura !
*Hugs* A warm welcome to you ~!

You can visit famous tourist spots such as the zoo, the birdpark , Night Safari & Sentosa (which is a offshore island) ~
Shopping-wise, Orchard Road is a good choice~
& for night life, you may want to try Holland Village ~
2 weeks is more than sufficient to explore this island of ours !
Just some suggestions...can't think of much at this time...

Enjoy yourself in Singapore !
