My Personal Experience: I went to Singapore Downtown Core last year September 18, 2015, together with my sister. We went there to round up our trip and have some down time in the city. In Singapore your never lost there's things to explore where you can find things that you never imagine and there's lot happening's it's up to you how to enjoy them.
Downtown Core
The Downtown Core is the historical downtown epicenter of the city-state of Singapore. It is one of the eleven planning areas located within the Central Area, which is often colloquially known as "The City". The name "Downtown Core" remains relatively unheard of and the term Central Business District (CBD) is commonly used in conversation instead.
