Corporate rates for a company are based on volume delivered, along with the stay pattern (if they pick up shoulder nights). These negotiated rates are based on the hotel/market/volume for the individual hotel. These rates have LRA (Last Room Availability) or NLRA (Non LRA). This is also determined on volume/stay pattern/total spending. Some of this LRA/NLRA are negotiated at the corporate level of Marriott, or are dictated by the company itself. Setting/acceptance of the terms is determined by the properties (they may be exceptions for project/special group business).
To my point. Each property forecasts room night volume/pattern/dollars for a given year prior to negotiating, or being including in the RFP/pricing process. For example, Company A might have a neg rate and LRA, but due to their stay pattern, that may not offered the nexr year (rate or LRA status) due to the actual use.
Corporations negotiate their rates in good faith with us based on these set of criterion. It is a partnership that Marriott enters into with our partners. It has to be a win-win, obviously. Yes, it is the individual property to ask for ID for whatever discount is booked by a guest checking in. You and I both know that doesn't happen frequently. I want our front desk people focusing on you (taking care of you, having real conversation, meeting your needs) rather than asking you for proof that you are a member of whatever corp/group you are with. This wouldn't sit well with me, and I am sure it would not sit well with you on a consistent basis. This should be standard practice (and is usually required by the neg rate contract), and I know that that stay at our hotels, mainly, are not the ppl that signed the agreement.
The big effect of misusing rate/corp codes - a property will not participate in a respective rate program, or if they choose to, they will not offer LRA or as a big neg rate.
I do appreciate all of our big corporate customers. However, this misuses at times can actually hurt they ability to negotiate a better rate for their company due to inaccurate information. They report X number of rooms for a given night of the week (YTD), and we show something completely differ. This does make it difficult.
Once again, I am not trying to just trying to give you the facts that happen during the pricing process, from MHO.
