That building is called Marina Bay Sands.
Where Universal Singapore is located is at Resorts World Sentosa, its a private property owned by the Genting group.
Sentosa Island is owned by the Singaporean Government (*i think).
Sentosa before Universal was lame, terrible simulators, lame mockups, a huge merlion (*replica), and an amazing water fountain show (*demolished down for USS).
The fountain show is now replaced with a childish and lame show, waste of my time and money.
Theres Wave House,you know fake waves.
Sentosa is a place for Relaxation at the beaches, more of a recreational place.
RWS (Resorts World at Sentosa) is more a theme park place. With overpriced hotels, worlds most expensive Japaese food (about USD$463 per person for tasters menu), new Joel Robuchon restaurants, a show at the Lake of dreams which is ok.
Yes, ive been there over 20 times, season pass:
Thats not actually mine but i got it from Dejiki (lazy for taking pics)
Also, Waterworld is part of Lost World or Jurassic Park
