Yes the balcony is very large. We had a cabin cavalcade so our group could see the various grades, eg. inside, balcony, mini-suite, etc. We concluded at 731 because of it being a mini and having the larger balcony so there was plenty of room for all. You are also down near the end of the corridor so the only traffic is people in your area.
