If you book a Magical Gathering, they will assign everyone in your group a gathering number which will be attached to your resort reservations, "linking" all of your info together. Everyone doesn't have to stay in the same place, and you can book the GG events yourself, just give your gathering number. We did the GG Wishes cruise in August and it is wonderful! It was about $30 per person, and worth every cent, I would not hesitate to reccommend it to anyone.
