Hi GadaboutGran, I went to Singapore in the early '80s, so am probably not as up to date as others who may have been there more recently. I do remember we went on an organised coach trip to Malacca, if I remember rightly it took a good few hours. I'm sure for shorter trips taxis would be good though. I do remember that it was the most humid place I had ever been to and having arrived there from Western Australia, where it's a very dry heat, I found it quite overwhelming at times. The hotels, buses and taxis were all air conditioned and I often felt quite cold in them and then stepping out into the humidity was sometimes not a great contrast. Nevertheless, there are lots of interesting things to see, loads of different cuisines to sample, great shopping and it is very safe so I'm sure you will have a great time.
