I went there.
And my advice for next year is DO NOT GO THERE!
I arrived at 11PM, we could notice already too many people for too few security guards. But I said :"we should be ok, singapore is very safe"
11:30PM my wallet was stolen by a runnaway guy and his partner. I spent the next 25 minutes trying to get back my backpack from the bag's deposit at the entrance, walking around with security guard trying to find my wallet and filling forms.
Next at 00:30 AM I saw the first confusion. No people hurt so far.
around 1:20 AM I saw the second confusion, this time 1 guy got totally beat up by other 3 guys. A few minutes later the poor guy came with his friends. General confusion stablished in the foam party for the next 5 minutes because these 2 gangs were fighting.
Around 2:30 AM another fight and this time 3 guys came to bother my wife. When then we judge better leave the party.
The outside area ,where the MTV guys were, was very quiet and peaceful. In fact, it looked much more like Singapore style. Very nice and cool music playing, and everyone just watching well behaved
Other than that, the party was ok (!?), but the foam party was definitelly 'outlaw's land'.
Next day, january 1st me and my wife we went to police station to fill more forms as suggested by sentosa guards. There we discovered that many fights complains were registered, so that foam party was indeed not a good idea.
My advice: next year find another place to go other than sentosa.
