If you have a couple of hours to spare one evening after a hard day of conferencing why not visit the world's first Night Safari at Singapore Zoo? You get to explore wildlife in a tropical jungle at night! And in case you're thinking zoo=bad, think again. Singapore Zoo is a model of the 'open zoo' concept. The animals are kept in spacious, landscaped enclosures, separated from the visitors by dry or wet moats. It's magical.
