None of these really make much difference to me, but you have several things to consider:
- Price
- Exterior View
- Motion
- Length of Walks
- Unwanted sounds
The ship's center of gravity is where you'd expect it to be...kind of in the center. Not top, not bottom, not front, not back. That's supposed to move less. But if it's rough, you'll feel it no matter where you are. And if it's not rough, it doesn't matter how close to the GC you are.
"All" the ships have the pool and buffet up on top and the dining rooms down low. There's usually a couple of public decks down low. I didn't look at the plan for your ship. I find that my trips are from the room to up top for the buffet, pool, and being outside. So if you're like me and you didn't want to walk a lot of stairs, you'd be higher up.
If you are at an extreme end (pointy or blunt), you'll walk a bit more. This wasn't a "thing" in the past, but the dang ships got so big nowadays. I don't care much...you need to work off all of the food you eat, lol!
Already covered, there are rooms above or below the "boom boom" of the disco, or the "slam, bam" of an external door, or even the "pitter patter" of the early walkers on the lifeboat deck. Also the mechanicals (engine noise is down in back and thruster noise is down in front). I kind of like to hear the engines...you know when you're coming into port.
Also, rooms adjacent to the steward pantry, crew hallway, elevators, etc. I've been near elevators and not heard a thing, and I've had "bad neighbors" and heard them returning to their room at the wee hours...nothing you can do about that.
