I think you have to report to Pasir Ris Bus Interchange if you
are enlisting.
There are no parking lots at the SAF Ferry Terminal. And also if
you are taking a bus to the ferry terminal, its more
troublesome.
You run the risk of being rejected and you might end up turing one
round by cab and end up in Pasir Ris Interchange after
all.

this)

You wouldn't get rejected from the RPs at SFT as long as your
attire is appropriate, just that they may question you and give you
warning, the most is they will call your company and ask them to
give you extra or confinement (at worst).
