Hi carebear
The info u require is quite P&C and further more, what's deem best to u might not applied to others. Also, the perks we received is based on several factors such as no of tables, weekday or weekend, type of menu, and in special cases, we give up some perks for others.
Wat i can advise u is that u weigh wat's important to u and ask from your coordinator. A general guide is asking for more seat for food taste, car park coupons n invitation cards. Good luck!
