Yeah, I've been to SIN and found it quite boring.
I hadn't been there yet when I booked the QR flights though, but for a night it'll be fine, and my gf hasn't been there.

Yes, it's a lot of traveling.
But I booked this on purpose.

Have a look at my recent initinerary above, I really like "seeing" (of course you only get a glimpse of each place) many different places in a short period of time.

But thank you all for your comments, much appreciated.
