I guess the question can be interpreted both ways, but I think the answer's the same.
I've negotiated 50% point bonuses for project teams of 10-15 people staying for months at a time.
I'm sure a property could provide an award room at a lower points redemption rate. It may require you booking it at the regular (20,000, for example) rate from Marriott and then they'd credit you 2,500 or 5,000 back. But it would have to be associated with spend similar to the above, and it seems like an odd request. I can't imagine telling my project team that instead of additional points for everyone I negotiated cheaper award stays for myself. Or even for the team - it would require wanting to redeem an award at a location where you've stayed for an extended period.
