hi feb07bride,
everyone's requirement is different.. some wan more wine, some wan more beer, some wan more roomstay, etc etc..
i feel u should look at the package which u intend to sign up, then go thru one-by-one if everyone meets ur requirement anot.. if not, u'll hv to tell ur coordinator what u wan for every individual items.. they are more than happy to go thru with ur.. if u need more help on what to nego, try doing comparison with ur recently-married friends.. they should be able to tell some nos, like no of wines / beer, carpark coupons, etc..
one thing i must warn u is regent is quite rigid in roomstay.. dun get too disappointed if they "refuse" to extend extra time or days ya!
