yup. take if you want to be 2 hours late.
There isn't much difference between either of those routes. And
you certainly can't be 2 hours late.
Woodlands -> Yishun is about 20 minutes. Yishun -> Tiong
Bahru is an hour five minutes. So your total travel time is about 1
half hours? :o~ Not including the transfer on 33/970/etc.
