You can earn a LOT of hotel points through Hilton, Marriott, Hyatt, even Holiday Inn, for booking meetings. Generally, though, you must occupy at least 10 sleeping rooms in addition to the meeting space. If you have the sleeping rooms, they will calculate the number of points you get based on the # of sleeping rooms used, the food and beverage dollars spent, A/V (sometimes, if it's done in-house). I do that as part of my job and it's easy to rack up 10,000 or more points for a single meeting. Good luck!
