5 or more rooms is considered a Group for most chains. All of the major chains offer points for the "planner". Rooms can be billed by one master account or individually. You just need to negotiate a good room rate. So- you get the points and saves your company $$$. Look under the "meetings" section of the websites and call the national 800 number. They can usually help you with just room reservations. Sometimes, they put you in touch with the hotel's sales manager. Hope this helps.
