Hi Amy---Haven't even gotten close to hitting 15, an now I am realizing how ambitious that was of me! We are currently only at three staterooms, and you are included! I am hoping to get at least a few more. It seems to me that this board is not the one that most of the others travelers on the cruise are using--I believe that they are on a social media site. But I am hoping to get at least a few more families on this board to join our group. I will post a final list on Saturday, Aug 8 so that we have enough time to pack and prepare. Even if we are a small group, it will still be fun!
