I will tell you that the 7208 cabins will be much quieter than the ones above the 70's dance club. We we on her in Dec. and spent some time in the club. It is wild, and loud till very late. We were on Empress deck then. In Sept. we are on Veranda deck. I would go with the forward rooms, as there will be little traffic in that area, and you have cabins above and below you.
Just my opinion.
Enjoy whatever you decide.
