If you've organized anything in the hotel's function rooms, the contract might or might not allow you to earn points on the charges, for example for F&B and room rental.
When I mentioned points/nights/stay credits, I was assuming that guests would pay for their own rooms and be credited accordingly by Hyatt. You normally cannot earn points on a large number of rooms, nor would you get nights/stay credits for rooms other than the one you occupy and pay. Read the Hyatt T&C to check these limits.
Will all of the rooms be on a master bill? That would further prevent earning points/nights/stay credits.
