Hypothetical question

What if a guest negotiates a long term deal with a hotel...good enough that the discounted rate for 7 nights is about equal to a regular rate (or corporate rate) for 3 nights. I know what the advantages are for the guest. But what are the advantages for the hotel? It seems they lose the potential for renting the room 4 nights a week at a higher rate. Is there some sort of incentive from Marriott HQ for the higher occupancy rate?

Just curious.

Thanks.
