Kona

I think I decided on the cruise and ship. Pretty much ready to book...so excited. The only decision is between two cabins on Harmony. First is 12580, but I read a review about another 12th deck cabin and they could hear chairs being dragged on deck even though it is two floors up. The second cabin 7206 which look like it has a bit bigger balcony which is nice. What concerns me is that on the deck plan for the 7th deck shows a big blank section in front of the room. Not sure what is there. This will be our 1st cruise in 30 years so want to get it right. Which one would you choose.
