Circle line won't be complete unless it is indeed a circle.
For me I won't travel to Dhobby Ghaut from Holland Village
station.
Neither will I travel to Chinatown from Holland Village via
Harbourfront and N-E line.
Neither will I travel to Orchard from Holland Village via Bishan
and N-S line.
Neither will I travel to Changi Airport from Holland Village via
Paya Lebar and E-W line.
Circle line benefits more to residents residing in the East than
residents residing in the West.
For me, at present I walk from Holland Village to Buona Vista
station. With CIrcle line, I may still choose to walk to Buona
VIsta station.
Circle line benefits those who work and study in and arond
One-North, NUS and Science Parks, for me there are already many bus
services that connect me to those areas.
I will probably see the true benefits of CIrcle Line only it it
connects from Harbourfront to Marina, and when downtown line
(interchange at Botanic Garden) is up and running.
it benefits you by having less people crowd around your
station.
