I know Hyatt has a Meeting Planners program that would allow you to collect Gold Passport points based on the number of rooms and total expenditures for the "meeting". Check with the sales office at the local Hyatt. In fact, "meetings" such as yours are totally negotiable. Call the sales office of whatever hotel(s) you are interested in and ask them about points/miles for the booking. You should surely get more than the standard amount as described in program rules, especially if the hotel does not expect to be full on your chosen dates.
