I don't think that there is any walkway there that can be accessed.
Here is one review of that cabin that I found ...
"OUR CABIN: We were pleasantly surprised to find our stateroom not too small. We had a standard category 6B which a bed (two twins pushed together), a vanity area, closet with safe, and small bathroom. The bed was really comfortable. It wasn't until the last day of the cruise that I finally figured out who our cabin steward was and introduced myself. However, he did a great job of keeping our room fresh and well supplied so I had no complaints. Our one complaint about our room is that it was in the very back of the ship which gave us a great view of the wake, but also was right above some mechanical things that created a GREAT deal of noise on port days. I don't recommend M265 for that reason.

Thanks for the quick response.... We booked our room as Oceanview guarantee so we knew we might not have the best... But neither of us are concerned about noise. We are at least away from kids, ex husbands, etc.
We booked a 6A guarantee on the Fantasy and ended up with 6b - cabin M263, the very last cabin on the starboard side. There was some noise during docking and a little vibration but nothing we couldn't overlook.
