I dont know how much you saw of Singapore since you were here last joewr, but things around here change rather quickly. Every couple of years or so, theres always a new building, mall or some site thats been given a facelift.
Scubakat, if youre looking at a long SI while here, then there are many distractions for your picking. One of course, as joewr recommends, is to try out the Singapore Sling at the Raffles Hotel. Then theres the food Singaporeans are known for their passion for eating, almost every hour of the day. Apart from going to the movies, thats about all we can do here
hehe
just kidding.
Despite the size of the country (approx 620 sq km/239 sq miles), there are actually lots to see and do here. If shopping is on your list, check out Orchard Road one long stretch of road
shopping centres, entertainment spots, restaurants, etc. If youre thinking about just chilling out, then its Boat Quay at night, Singapores watering hole along a stretch of the Singapore River. Big herds of expats and local yuppies gather there in the evenings after work, busiest on Friday nights.
And then there are your normal tourist attractions like Singapore Zoos Night Safari, Jurong Bird Park (with the worlds highest man-made waterfall) and something closer to home, the Underwater World. Nothing compared to Australias or other oceanariums around the world, but visitors can get to dive with the sharks and feed Eagle Rays for a fee.
