Here's a picture of an open divider on one of those 4E extended veranda cabins. .. it also shows that the cabins are grouped in some way. In the upper part of the picture you can see how railing swings back in toward the body of the ship between two dividers.
If I had to guess, since your two cabins are the last two of the 4E cabins on the port side, yours will have a divider that can open. Enjoy those extra large verandahs !
