Come on, lay off him!
The guy's my hero.
Being perennially short on time, I have myself done a bunch of crazy short visits (e.g., seeing Osaka - my first Japanese city - in half a day; flying in early in the morning and departing on 1350 flight).
I once contemplated doing a hop from Washington DC to see Los Angeles for about five hours and flying back, but then I didn't because I needed to fly to meet someone in Chicago that day.
The world is full of hotels where I barely touched my pillow because there was so much to see in less than two days...
Your idea of SIN in two hours is superb. I would go for it in a heartbeat. Get a good taxi driver and tell him what you want to do.
