Contrary to what I said about discovering new places while travelling, Singapore happens to be one of those places that is rather difficult to lost because of the well organized Metro and small size of the country, plus there are lots of landmarks and most people can speak English :)

Not sure what is on the itinerary of your trip, but last time I was in Singapore the Red Dot Design Museum was closed, and I didn't get to go to the Cat Museum (I did get to the Toy Museum though). Gardens by the Bay is just beautiful and there are also lots of attractions around Marina Bays to take in but I didn't have time to go to :(
