This was our 1st cruise. From start to finish we enjoyed it so much we are already looking forward to our next. Our cabin was very comfortable, kept spotlessly clean by our Steward Joy who left us towel animals each night, from puppy dogs to elephants, an eskimo an even a little mouse peeping out of a cup. 10320 has the bed near the door, from other reviews I can see that the bed near the balcony doors is preferable as they give more space near the door / loo area, but we were fine in ours. The aft facing balcony was the winner for us, a little noisy at night because of the engines but earplugs meant I didn't hear the noise.
I did like being rocked to sleep each night by the ships movement, it was very comforting. . In this cabin you are awoken each morning as the ship approaches port and docks, you can feel the change in movement and it gently wakes you up. Just choose whether to go out to the balcony and watch or go back to sleep.
The view from the balcony is amazing, when we approach ports its like the bay encloses the ship and you see more and more of the land as it docks. Coming out of port you can see all the shore lit up as it disappears from view.
Loads of storage, bed near the door meant more room near the balcony. Coffee maker, supplies regularly topped up. Well worth the extra for an aft facing balcony. Superb views. 10320 doesn't have a larger than average balcony but in my opinion aft facing are superior. A bit noisier and a little more vibration at the back but not enough to be a nuisance.
