We are heading out on the Oosterdam in 2 weeks. We too get Aft cabins but our friends get interior cabins and then rent the cabana for the whole cruise. That's worked fine until now.. 3 weeks before the cruise leaves and she was just notified that a storm had damaged the cabanas and they are no longer available for the entire length of the cruise. So a cautionary tale that you may suddenly and without warning find yourself without the outdoor space you were relying on.
