Grandeur Deck 2 aft cabin

We are newbies to the cruise biz, and just booked a trip on the Grandeur. We have oceanfront cabin 2634 which is way aft.....Now we are wondering whether we will hear a lot of engine noise/ or feel a lot of vibration. Has anyone had this cabin, or one close to it before?????? We are wondering whether we should try to switch to another cabin, even an interior one.......

You might want to ask this on the Cruise Line Board.
