Saw a listing on icruise.com for a 6A cabin on the Riviera deck that listed a railing. It was NOT the 5A, obst. view, french door type. I haven't run across this before & Carnival was puzzled when I phoned them. Anyone know something they or I don't? Is there such a category? From what I can tell, the 6A cabins are merely regular, outsides. Must be a mistake??
