Nah, I'm like 99% sure the bedrooms don't have run in between them. Each bedroom has one wall that doesn't have any camera run windows: the one that joins it to the other bedroom.

Also notice the rectangular indentation with a camera in it in the wall of the main bedroom, and how the second bedroom has a dark rectangle in the same spot (With no camera or indentation). Seems like the indentation takes up the full width of the wall, leaving no room for one in the second bedroom. This extra camera angle is probably the reason why the main bedroom is used as the main bedroom. Again really awkward, space restricted design.
There's also an indentation for a door in the second bedroom that lines up with a door in the main bedroom. All the evidence seems to suggest that there is no space in between the bedrooms.
Also, the short hallways the housemates walk through to enter the bedrooms both have doors on either side of them. (You can see one of them in the main bedroom pic) They would be the doors that would be used to access the behind the oven camera run area.
