Singapore Flyer
You might be thinking: "But, nobody goes there anymore!" Which is exactly why you should go there, to get the best views of the fireworks in the sky, while you're in the sky! (Well, sort of.) We can't guarantee that there won't at least be a crowd of people at the flyer on National Day though, but hey, to view fireworks from the world's second largest observation wheel could prove to be worth it. The drawbacks would be getting the timing right and dealing with the possible crowd.
