The label "Marina Bay" is a little fuzzy. Technically, it's the body of water created by reclaiming land around the mouth of the Singapore River and blocked off from the sea by the Marina Barrage, but Singaporeans associate the name "Marina" with the Marina Square shopping mall and the many hotel developments around it on the north shore of the river. The half to the south of the river, or Marina South, has to date been just empty land dotted with construction sites, but its centerpiece, the Marina Bay Sands casino and convention center, opened in April 2010 and there's lots more to come. In this article, Marina Bay is simply defined as everything to the east of Shenton Way and Esplanade Drive.
Transport to Marina Bay remains a little disjointed. The northern half is best accessed through the shiny new Circle Line MRT (opened April 2010), which has stations at Esplanade (Suntec City) and Promenade (Millenia), or you can hike for 15 min through the underground CityLink shopping mall from Raffles City (City Hall MRT, where the North-South and East-West line intersect).
Getting to the southern half is more difficult. The Marina Bay Sands is directly served by the Bayfront MRT station and buses 97, 106 or 133. The same buses also serve Marina Bay MRT, which (despite the name) isn't particularly convenient for anything else just yet (except the Marina Barrage where you need to take a shuttle bus from the station to the said attraction). The Downtown MRT line is scheduled to open its Marina Bay stations in 2013.
From the airport, Marina Bay Sands hotel guests can use a 24-hour shuttle bus for free, but all others need to pay S$25 — nearly the same price as a taxi.
Marina Bay Sands Casino, . 24 hours. Singapore's second casino, larger and glitzier than its family-oriented competitor on Sentosa, with 600 gaming tables and 1500 slot machines.

Sands SkyPark, Marina Bay Sands (Tickets from hotel lobby, Tower 3), . 10 AM-10 PM. Singapore's single most dramatic landmark, the SkyPark defies gravity, perched 55 stories above the ground like a surfboard on top of the three hotel towers. Views aside, for time being there's not much bang for your buck though: the pool is open to guests only. The alternative to paying the entry fee is to visit the restaurants (see Eat) for lunch, which will set you back around $50, but you can freely explore the SkyPark afterwards.$20/14 adults/children. edit
