Since large association conventions can book their events years in advance, it's next to impossible to predict how many meeting rooms to reserve. The Produce Marketing Association ( overestimates its meeting-room needs and then rents out the extras (generally the rooms in hard-to-find locations) to exhibitors in half-day time slots for board meetings and presentations. PMA doesn't make much money from it, but the group doesn't lose money, either, and the practice keeps exhibitors and attendees in the convention center, which is especially important in cities laden with distractions.
