Singapore for work because that's the rule
Singapore is like the NYC of SEAsia. It's the big brother, the organized one.. the other countries look up to it. So it's naturally where all the grown-up stuff happens like finance and fancy buildings and conferences.
I spent 4 days there at a UX conference. While nobody wants the details of a conference (even in their own field) I will tell you that the people I met and the conversations were almost more helpful than the conference.
I obviously did conferencey stuff like sitting in cold rooms and standing around chatting in lobbies, but we also did some conference-ditching stuff and roamed around Singapore.
The fancy camera, heretofore known as HammerCam, came with me so I have some quality snaps of the skyline.
This area hosts all the middle-eastern, Indian and generally colorful vendors. I got some nice batik fabric and regretted not buying a caftan. One day I will be a caftan kind of woman.
The #1 view of Singapore is the mahoosive Marina Bay Sands, which you have to visit if your want to get you passport stamped. We also saw it from Level 33, which is allegedly the highest brewery in the world. Claims have not been independently verified an a beer was $17
We got a group going to cycle around the waterways of the city. Danny (California) and I cycled up and then down the river but dragged our bikes up and down stairs more than we cycled. After a cheap (by Sing standards) lunch we tackled Marina bay and Gardens by the Bay.
