We just got home from spending a week in Room 6309 on the CARNIVAL PRIDE and highly recommend it.
It was more spacious then as described and had all the amenities needed for comfortable cruising. Some of the better features were the nice sized balcony - room enough for two with cocktails and books. The balcony door was thick enough that there was no outside noise coming into the cabin.
Being on the vessel's starboard quarter (aft) we had a nice look at the sunset while travelling south and the sunrise on return. The location of the cabin is just about ideal also as it is located aft of the last set of elevators (a short walk forward) so it doesn't have any foot traffic other then others who have rooms in that corridor. It was very quiet - more so than we thought it would be.
Room 6309 was great. Quiet and easily big enough for my 6"6" frame, balcony held two with room to spare.
