i share my experiences..
went on may 14 saturday:
reach woodlands at 11am. causeway was somewhat "smooth"
clear kastam at 1.30pm. (queue for 2hours)
Analysis: kids exams ended + past 2 weekends we have campaigning +
GE.. many sinkies having the JB syndrome.. all one shot chiong JB
on 14 may + commencement of the fingerprinting system
went again on 28 may saturday
reach woodlands about 10.30am. causeway was quite OK
clear kastam by 11.45am. (stuck in queue for 1 hour)
this time, picked the shorter queue (pick the queue also involves
strategy)
was also the first day of kids holidays.. so sure have jam
one..
tip: from kranji, take 178 to sheng shiong. dont wait for
`160/170..all playng ninja.. freq is >10mins/bus. at
woodlands, take CW.... save money or save time. you choose
return trip at night: take 170. CW buses have freq at 15-20mins
duiz, when big jam 178 equally erratic. I've ever waited 30 mins
for 178 before.
Woodlands tat side take CW faster cos they bo chup you prev took
CW1, CW2 or CW5 or walk in.
But tis Sat jam, CW equally ninja or even worst than 160 or
170.
Normal time only 8 - 10 buses for CW1 no driver layover,
jam sure jialat jialat one.
Even on Fri, alrdy noticed CW5 freq is not even 15 - 20
mins, it was 35 - 45 mins
