I think during the slow season, they run specials on category 11 guarantee rooms as a way to fill the ship, and lots of people get upgraded, I know this was the case on our Sept.18th cruise. We booked 2 guaranteed category 11 rooms for my family, and friends we were traveling with booked 2 guaranteed category 11 rooms as well. We knew there was a chance we'd wind up all over the ship, but as it turned out, all 4 rooms were upgraded to category 7 navigators verandas, all next to each other. So Disney did manage to keep our families and friends together, even though someone posted that this would not happen with a guaranteed category 11. In fact, my thinking is it might have even helped us get that great upgrade!
