I went there by monorail. The monorail station is at VivoCity Shopping Mall.
You can purchase your monorail tickets from these machines. But if you preferred to purchase the monorail tickets together with the admission tickets to attractions in Sentosa, you could get them from the counters. The queues are long because of the flower show during chinese new year. Normally the queues is not that long.
You dont have to wait very long for the monorail trains.
On arriving at the beach station, you can take the trams to go around the island. I dont want to get stuck in the queues so I choose to walk to Palawan Beach from here. Only ten to fifteen minutes walk from here.
