Great balcony with fantastic views (minus all of the trash people threw over). Pretty noticeable vibrations when docking, but it didn't bother us. Room was a decent size (much larger than others). Hallway was noisy, but we will attribute that to obnoxious people. Read entire member review.
We booked a port side premium extended balcony on the Verandah Deck (Deck 8 - Cabin 8428) and man did they mean premium. The fantail balconies are huge on Carnival's ships but those on the back corner are enormous with the largest two being one either side of the end of deck 8. The cabin itself was roomy with a queen bed, large couch, plenty of closet space, drawer space and a bathroom not too large but not too small (got spoiled at the Hilton) but the balcony had more square footage than the room itself which proved fine by us as we spent much time there luxuriating in the view and the peaceful haven it gave on a ship with over 2000 people aboard.
