I stayed at a Marriott on Tuesday night and noted a 500 Bonus points are provided IF you are staying more than 1 night at the same hotel and do not want house-keeping service. Apparently this 500 point bonus is per night because on the door-hang (which must be displayed by 0200hrs) it states to display for each day you do not wish to receive the service. I do not know if this is rolled out to all Marriott properties.
I think this is a win-win for both. Marriott reduces costs and service (only if the occupant wishes it so) and the MR member receives a 'thank-you' for reducing work-loads and environmental waste.
GOOD JOB MARRIOTT! I hope this applies to all of your properties because next week I have a multi-night stay in Washington and plan on taking advantage of the 500 point offer while doing my part to help reduce environmental impacts. Phil
