Halloween in Singapore (near the American school, at least) is more American than you'll find in America. The locals come out to experience it as well (which is only fair since we go out and check out all of their holidays!). I purchased 2000 pieces of candy (from a nice woman in the neighbourhood who coordinates a bulk order each year) and gave out one piece to each person who came to trick-or-treat. It was non-stop action! The locals seemed particularly impressed with the jack-o-lanterns and my super-simple skeleton costume. We got lots of pictures with people, too. Overall, it was very chaotic but fun. (I do think I chose wisely and stayed home to pass out candy while Craig braved the streets with the kids--and he had to come home early from work to ensure he could drive into the neighbourhood before the streets were closed off).
