My AD is on 26 July 2015.
I have done some comparisons with different hotel venues in Singapore, you can check out my reviews to see if MBS is the one for you -

Personally for myself, I thought their basic package together with their 1 wedding wish was very tempting already so I didn't request for much things. I chose the 1 additional night stay at the suite as the wedding wish and in addition I just asked for free corkage of 5 bottles of wines and preferential carpark rates for guests (they say they will let me know the rates, will follow up with them soon). Haha i'm not that good at bargaining. I chose it purely based on my liking for the venue and the suite hahaha.
