Is the free bus from Sentosa Island to downtown still open?

Yes, it is running normally at present.

There are three free buses from Sentosa Island to downtown, one from Orchard Road and one from Jinsha Hotel. I can't remember, but not everyone can take it. You must stay in a designated hotel and get it with your room card. I was staying at Jinsha Hotel, and I used my room card to take it twice for free. The driver checked it carefully.
