I have spent two days independently in Singapore en route to New Zealand, and am going again next month en route to Oz. I think it is a wonderfully interesting place, of course it may not be for you. Look up on the internet and see the variety of places and areas. I am not a foodie but if you are, it is a paradise. I did a half day coach tour which included the orchid gardens. Also did a boat trip with commentary on the river and went to the history museum (wonderful break from the humidity). This time I plan to explore chinatown and visit the new gardens made from reclaimed ground. It is full of history, visual experiences, museums and - if it is your scene - shopping malls. Also a highly recommended zoo, bird park, night safari etc none of which I went to. It is also a great way of breaking up the long journey and visiting somewhere different.
