Basic admission to the island will set you back at least $2 per person which is included in the transportation fares from the mainland to Sentosa. There is an ever-changing palette of combination tickets that may work out marginally cheaper if you plan to visit multiple attractions. The island itself is open 24 hours a day, 365 days a year, although many of the attractions are not.
The best way is in to take the North-East Line of the MRT to HarbourFront and then make your way to Level 3 of Vivocity, where you'll find the Sentosa Express monorail to the island. The train operates every 5-8 minutes from 7AM to 11:45PM daily, and an round-trip ticket costs $3 island admission included, EZ-Link accepted. The cheapest way though, is to take an SMRT bus (http://www.smrt.com.sg/bu...) for $2:
RWS 8
from VivoCity/HarbourFront MRTBy taxi or private car, you'll need to pay $2 to $7 per vehicle to enter, and a $3 taxi surcharge also applies on the way out. It is now possible to walk across the bridge via the Sentosa Broadwalk $1, EZ-Link accepted (http://www.sentosa.com.sg...) .
The Cable Car (http://www.cablecar.com.sg) between Sentosa, HarbourFront and Mt. Faber has completed its renovation and reopened to public in July 2010.Return ticket on Cable Car costs $26.
Sentosa's ferry terminal has been demolished to make way for the casino, but there are still limited ferry services (http://www.yorklaunch.com...) from Singapore's Marina South Pier bus 402 from Marina Bay MRT to the southern islands of Kusu and St. John. Monday through Saturday, there are two services a day, leaving at 10AM and 1:30PM, looping to Kusu, St. John, Kusu again and then back to Marina South. This gives you one hour on Kusu, which is plenty for seeing the sights. On Sundays and holidays only, there are five services, at 9AM, 11AM, 1PM, 3PM and 5PM, which run to Kusu, St. John and then return directly to Marina South, giving a minimum of two hours on any island you go to. All ferries cost $15 return, no Sentosa entry fee needed.
