bro, used wrong word liao..not "tio"..means i use same approach..
sometimes tourist not familiar to make informed choice..so i wl try
to understand their needs..do they wan to com so far to sgp to b
cot in jams counting diff models of cars on our roads.. of course
som tourists also don need to be kay khiang for them lah..
Ya, actually I meant only for Airport approach..........not
target at you lah.......
Maybe my last few years was driving white, so very particular on
route in and out of AP..........
Anyway, CDG system can actually trace from the point you pick up
until the point you drop off, regardless whether on call or not, if
sway sway we re-route and tio jam also, pax late for flight, angry,
complain..........check back, why you go 1 loop? Hahaha, jump into
yellow river also cannot clear..........
I don't say is a must to use this route, ah Khoon was right,
from Hyatt coming out, u-turn at Orchard Boulevard, go in Steven
Road after Royal Plaza on Scott, not turning right to Cairnhill,
from Steven Road, all the way liao............
Tourist, once on board at AP, I will ask them " first time in
Sg?", if yes, regardless where they
go.........ECP/City..........why?, once approaching Sheares Bridge,
they see our skyline, WOW! And that's the timing, my parang come
out liao......... 
PIE? Knn, nothing to see leh.........lol
