We are sailing on the Grand Princess June 17 . We were upgraded from a category G obstructed view to a category D on the Plaza deck. The brochure says this room can accomodate 3rd and 4th persons. So does that mean that this room is a little larger than the category g. Any information you have about this room or this deck on the Grand is appreciated. We booked a category G on a garuntee and although it would have been just fine, we were thrilled to check the cabin assignments and get an upgrade. One week to go.
