I don't know what you're talking about. If you'd rather not walk that far (it isn't far but say it's raining or it's super hot) and that's also a quick bus ride away.

Also, the "metro" is great but it can get crowded like any train can during peak. You gotta qualify what you mean by "unless you happen to be on the right line."

Singapore is always the same temperature -- very humid and 32 degrees during the day. It's never super hot (temperature record is something like 35), but it's always hot and muggy and about to rain.

I used to walk from Sim Lin Square to Raffles, less than 1km, always regretted it.

Clarification would be if you didn't have to change. If it's a 10 minute taxi or 2 metro changes, I know which I do in SG. I commuted from Haugong via taxi for a month rather than take a bus/metro/bus
