In fact, as JerryFF mentions, meeting planner bonuses are part of the negotiation. Hilton offers them too, generally with a minimum of 10 rooms on at least 1 night. They use a (seemingly) complex formula to compute how many points to give you, and Saturday nights are definitely worth the most points at business oriented hotels. Enjoy! It's worth using a card that gives extra miles too. For example, at one larger meeting I booked at a Hilton I got about 20,000 Amex MR points for paying the $10,000 bill on my Amex in the first year of membership (double points with affiliates), plus almost 50,000 HHonors points.
