Carnival Spirit Aft Cabin question

[Bebeeann]

Hello:

We are booked on the Carnival Spirit and have booked Cabin 7300 aft. We are wondering if anyone has been in an aft cabin and can give us their comments on the aft cabins in general. Also, how are the balconies are they larger than the regular cabin balconies? We have also heard that sometimes it can be hot on the balcony for aft cabins, not much of a breeze and that sometimes you get vibrations or soot from the stack. Has anyone heard or experienced any of this? Thanks!
