It should be obvious by now that your marketing gurus have failed to convince anyone that you have done something good for your customers. The loss of the week long awards structure is very painful for your most loyal customers (high points accumulators). Second, the no blackouts ploy is a joke. By simply making one room available at all times each facility satisfies your no blackout requirement but everyone knows one room's availabilty is almost totally meaningless.
Try again and this time please think of your customers. Look for a win-win not just a Marriott wins and the customer loses big plan
