My wife and I were very lucky to get Alvin as our tour guide.  He's kind, friendly, smart, and has a great sense of humor.  He really cared about us and made sure we had a great time and went out of his way for us.  We saw EVERYTHING possible in Singapore and his knowlege and experience was indispensible.   We felt very comforable and by the time we left, we gained a new friend on the other side of the world (we're from San Diego, California).  We did all of the tours he offered, including a night tour to see the lights that were put up on the Chinese New Year..
