Marriot - 1028 (table of 10)
Pan Pac - 1058 (table of 10)
Oriental - 938 (friday) 1138 (weekend) (table of 10)
I don't have the rates for intercontinental.
Marriot rates may be inaccurate, cos the date i asked was a auspicious date, and they do charge extra for that.
When we went to pan pac, the coordinator was a bit inflexible with the perks, so it depends on who you end up talking to. But 35 tables, may not be enough for their main ballroom.
Oriental was our first choice hotel, but totally our of the budget, and we were not looking at the friday option. After the ++ part, per table is 1339.
My wife and I picked Conrad.
