Plz note the actual date of this day tour was on Aug 23rd, 2014.
We bought Air Asia air tickets two weeks before boarding to Singapore. It costs us RM207 return per pax. If you lucky, you may get cheaper than dat! We bought the USS entrance tickets from a stranger that we found in Backpackers Buddies Malaysia (BBM). She charged RM120 per tickets and she had two tickets. We bought both from her and another two more from travel agent (RM150 per tickets). For those, you may buy from RWSonline or for cheaper rate by coupon.
We depart at 7.40 am and it took an hour from Kuala Lumpur to Changi Airport, Singapore. We ride on three variation trains from Changi to USS and it took more or less an hour. We ride on skytrain from Changi Airport arrival hall to T2 (Terminal 2). The skytrain operates from 5am till 2.30am. [Tip1: During non-operating hours, they provided free shuttle bus service at T1 Departure Hall Door 5 (near row 14)].
