We are a family of five booked together in one stateroom. My aunt has decided to join us and booked her own room. She is willing to pay the price of 2 and just stay by herself. I was thinking of moving one of my kids to her room just on the reservation to save her some money. We done DCL with big family groups before so I know I can add all adults to be able to check kids in/out of clubs and take them on/off the boat and we will do that no matter where the kids end up on the booking. My aunt will be linked to our dining reservations as well. Will I be able to move DD back to our room once onboard? Are there any other issues to consider with this? I've had a child cruise in my parents room previously also but they stayed in there because we didn't have a room for 5 available.
