I too have spent a lot of time in Singapore, both working and living there. I first went there around the mid 1970’s to dry dock a ship. The original dockyard was at the base of Mt Faber, which is now overseen by the cable car to Sentosa. At one time the biggest graving dock east of Suez.

Also docked a ship in the King George 6th graving dock at Sembawang. (that's not me in the front row)

The place has a lot of old colonial history if you are interested. Also spent some time at the old British Army base at Changi, where you can see fine old colonial buildings.
I cannot agree with Vincent about Sentosa. If you had any family in WW2, then it is a must visit place.
But modern Singapore is not the same place it was in my times! Ultra-modern glitzy shopping centres, surrounded my lush green gardens. A place where everything works and is maintained.
A vast user friendly MRT train system that runs very nearly over the whole island. Senior people are respected and young ones will trip over themselves to give up their seat if crowded.
It is NOT a cheap place, either to live there, or just visit. English is spoken in most places, including taxi drivers! All taxis have meters, and credit card payments are normal.
It is hot and humid, pretty much all of the time, so carry a bottle or two of water.
