If I am not wrong, this is a special local rate hence it might be a rate negotiation by your corporate travel manager (fortune 50-100 tends to negotiate harder) where the points and benefits was exchanged for possibly a lower rate.

You and your colleagues could contact your Corporate travel manager to complain (such that they include this in the negotiation for the rate next year) and feedback to the hotel sales team (they want your business so they have to convince the GM to give the benefits)
