I LOVE the back of the ship! There's a little more rattling, but the view from the back is amazing! Plus, you can actually tan in the back. The balconies are equipped with lounge chairs you can lay in and tan. I'd suggest trying the back -- you'll never want a room anywhere else!
I'm on the Triumph in November and was able to get an extended balcony room (catagory 8a) for only $649 (past guest member price). Some people don't know, but there are extended balcony rooms on almost every ship - all you have to do is ask! My room is L shaped, more closet space, more windows, and 90sq ft balcony for the price of a regular 8a balcony with a 35sq ft balcony. Ask, and you shall receive!!
