Just submitted 8 forms on behalf of our group for our wedding cruise this fall. Looks like a $100 discount per room. We have 7 balcony rooms, some have 2, 3, or 4 people, and 1 interior room with 3 peoplem, all on Deck 9. Same discount for all of our reservations, so it seems the room type and number of occupants is irrelevant.
Yeah free money!
