Of course the other thing to do in SIN - just like most of the rest of Asia - is eat. Satay anyone?
Which is the main thing I do in Singapore (oh and drink!, but beer isn't as cheap of course).
Actually I like Singapore because it's safe, clean, the food is normally well prepared (and not very likely to give you food poisoning) and getting around is pretty easy.
Keep in mind a trip to SIN for me isn't just a trip to SIN. Why take the short way to somewhere when there are equally as good longer ways?
