Monitor, if you are coming all the way to Singapore on an award ticket, I'd urge you to add another Asian city to your trip. It's a lot of miles to burn and a long way to come. The appeal for many of us is exactly the distance - it is a wonderful way to kickstart the quest for status. However, you'll be burning instead of earning. Of course, if you love to fly, then it is a great way to enjoy the treatment in a front cabin.
Consider Bangkok or Hong Kong, for example. Or if you are an Asian expert, you can be a little more exotic. I used Singapore s a jumping off point for a 3 day trip to Borneo two years ago.
Also, be sure to take the Singapore Airlines bus tour. It is about a 90 minute overview of the city; well worth the $5 or so that is charged.
