Carnival is re-segmenting the cabin categories. They are going to separate the forward and aft cabins into additional categories. And there will be additional categories as well. This will take effect today for new bookings on the Valor. The rest of the fleet will be phased in by the end of 2008.
Yes, the balconies have new categories too. The email they sent me said it was an opportunity to up-sell the categories, meaning there will be price differences now. Just more confusion most likely.
