They will only be two door from you cabin. They'll be alright except if they all want to use the bathroom at one time. Maybe you will be able to them use your shower once in a while. You're going to have a huge balcony for them to share with you once in awhile too. I know they won't be in their room too much, so I wouldn't worry about them. One tip would be to have them store small luggage inside larger luggage and store as much as possible under the bed. The next best scenario would be connecting cabins. Your travel agent probably has talked to you about that.
