Sorry sorrry, I did not put clearly. i actually mean people whom dun have to be ties down in Singapore, if time allows, actually flying to KL is quite easy & affordable via jetstar.
I have been doing that for the past few months. Cos I stay in the east, so going to Changi Airport is easy. jus reach 40min before flight time, walk in n board. an hour flight, sometimes even faster, have timed before they k reach in 30min if they wan to fly fast to catch up. then jus hop on KLIA express to KL Sentral n for me I hop on to LRT to KLCC. abt RM36.6, cheaper compared to taxi n time more predictable.
the weekend in KLCC is quite nice n relaxing, with less traffic. what I like is the convenience to stay within short proximity to 5 star hotels n walking distance to KLCC & Pavilion. alot of meal and chillout options. or jus enjoy a personal training session at RM80 per hr at mandarin oriental and use the pool and facilities after.
