Hi Jacqueline,
Based on my past experiences (old shang bride), the perks are pretty standard.
However the more tables that you confirm, the better the perks will be.
I remember for me,65 tables, shang up my parking coupons to 40%, 1 extra night stay, lower cost for cockage, better pricing for barrels of beer, discounted rates for guests if staying overnight.
Cant totally recall the details... Normally such established hotels dun give any fantastic perks
