I believe the average stay in Vegas is less then 5 nights. I don't think the major strip hotels negotiate for rates unless huge volumes are involved. He might find special rates at places like Extended Stay America or Marriott Residence Inn.
That said, he has nothing to lose by calling each hotel and asking to speak with a hotel operations manager.
I've got a contact at Venetian, if he want to contact me direct. My email address is on my web site.
