Odyssey OTS - What's between cabins 12692 and 12694

[RoMoAhoy]

While looking at the deck plans for the new RCCL Odyssey of the Seas I noticed a void between cabins 12692 and 12694.  This same void shows on decks 6 through 13 as well and on both the starboard and port sides of the ship.  It is not there on the other RCCL Quantum class ships. 

We are booked for cabin 12694 for a December cruise and want to know what we will be dealing with. 

One possible option is a water-tight safety door which should not affect our experience.  Other thoughts include some sort of utility chase or air shaft.

Looks like it could be an exit door for crew - they probably get to the Cleaning Equipment through that door.

Just guessing.😉
