We just got home from Bitan and it was perfect.
We walked along the water, grabbed a pizza, and set off our own lantern… Mom, Dad, and the Baby loved it - just what we wanted.
As Sandman indicated, very low key and no crowd. There wasn’t any “festival” per se, but there were lanterns available to set off ($150) and kids were shooting fireworks. I’m sure the lantern sellers will be there on Sunday.
If this sounds like your type of fun and want to check out Bitan but have not done so yet … take the green line to the end (Hsintien), go out of the MRT and hang a left over the stairs. You should see the river and suspension bridge. Pizza cost ~$225 and could feed 2 (we were hungry and got 1 each) - we were pretty much the only ones there eating early and had no trouble getting a table overlooking the water, the lanterns cost $150, they have paddle boats, people fishing along the water, lots of kids, plants, birds, and plenty of space.
