hi blur,
just to supplement what oraia said, the food at hyatt was nice!! that's the comment i got from most of my guests, and one of my halal friend commented that most of the time, when she went to other hotel for banquet, they are kind of chin chai on halal food.. but the one at hyatt is actually good... according to her..
regarding to deco, i just went with what hyatt provided, added nothing on top of that, and i think it was good enough...
and yes, both hibiscus and SSR room have it's own reception area...
