not disorganized at all! The day before the first cruise ends, there will be a meeting for all b2b guests. at that time, you'll receive your new key card and be able to make any dining reservations you want and also buy your beverage package if you like. The next morning, you'll be asked to go to security at the door and check out with your old card; at that time, you'll activate your new card. Let the desk know that you need to do it as early as possible in order to meet your tour. They've always been very accomodating for us 🙂
