We stayed a couple doors down on the Wonder last week. We stayed in 7128 which is also a Navigator's Verandah room. DH and I both loved the room and the location was great. I didn't notice much hallway traffic noise and I know the ship was booked full so there were definitely full cabins all around us. We apparently had some runners or jumpers above us, though, because we heard quite a bit of noise from up above, but not enough to ruin our trip or anything like that, just enough to notice.
I especially liked this location on the morning of
Castaway Cay because I had a great view of the dock while we were backing up to it. Come to think of it, I remember leaning out the verandah and noticing people a few verandahs down watching also, and I bet they were in 7124 so you'd probably have a good view of this also if you're interested.
It was also a short walk to the aft lifts (and stairs which is what we took most of the time!) and 7124 is even two doors closer!
I'm not sure if there's anything else I can help you with about that location on the ship but if so, just let me know. Sorry I can't comment on the specific room.
I will say if (when?) we ever go on another cruise I would not hesitate to request the same location again!
