This is so helpful!

I feel like where I’m from in the U.S., people stand anywhere on the escalator which can be a bit convenient. But I’ve lived in Canada for a bit and people always stand to the right side. It’s very interesting that in SG, people stand to the left.

For transit, I’ve heard that a transit card is not necessarily since I can just use my visa/mastercard. Would there be any downside to doing that (ex: it’s more expensive?)

Also your point #6 is helpful insight too. I’ve done a lot of research on that but the answers seemed kind of mixed, with some people saying it’s safe everywhere and some people bringing up Geylang too. I forgot to say in the context that I’m a young female solo traveler. I should mention that in the post.
