Christmas Wonderland [Source] is a Christmas festivity held yearly at the Gardens by the Bay since 2014. There's lights display, food trucks and live performances, giving the place a very Christmas-y atmosphere.
This is the first time that I've been there for the event, despite it being held since 2014. I enjoyed myself there, with fairly good food, live music and great atmosphere. There weather was generally cool too, though there was short spell of rain shower that dampened the atmosphere a little (I was prepared with my poncho). I also had a fun time with some long exposure photography, as I was able to capture some nice moving lights before the rain shower occurred.
I do think I'll want to attend the event again next year if I can.
