eh, just do it. a long time ago when suddenly one day, I decided to go for a train ride Sing to Jb, simply went to Tjg Pagar rail stn, buy the ticket at the counter, pop on the train, go JB, alight (hop off) somewhere near to Holiday Plaza shopping (dunno if they still allow this now)
how come you agonise over something so simple, easy and riskfree.
