Group Contracts at MP--- anyone have extensive expereince with this?? We're not sure how many rooms to book or for how many nights. The hotel wants the # of rooms and the specific dates of travel, but we don't know when our guests are going to want to travel. We're offering a 3, 4, and 7 night package, but some guests are of course going to deviate from that plan... any suggestions or advice would be greatly appreciated!
