faya,
I don't think so, i had a pleasant negotiation with Dannis from Raffles the plaza. He is very nice and prompt in calling me for appointments. He send me the proposal with their schedule programs and wedding songs for the night and he is also flexible in the no. of tables that i book. And he also has contacts for cheaper wines, beers, musicians, projector rental whereby no commission is earned.
He is also very generous in the perks he gave to me, more that what other hotel is willing to give me. do you mind if i email to you the perks that I managed to negotiate with him because I do not want everyone to go and ask him for the same stuff. Not very nice and fair for him.
