You don't have to be a spouse to get the 2nd room either though. If your child is an adult they qualify for the 2nd room so long as the military member and/or spouse are going on the same cruise. They have to be immediate family though. So great Aunt Edna can't get the 2nd room under the military discount, but the adult child could. My point was to the previous poster that said you could only get one room now, that's not actually the case. Technically, if you have 15 children, you could get as many rooms that you need, so long as an adult is in each room and those adults are immediate family members.
