If you think about it, that analogy doesn't really work. The rooms that guests stay in are almost all along the outside because guests are paying customers. The janitor's storage rooms, room service kitchens, elevator shafts, mechanical access corridors and other such workspaces are located on the inside in the less valuable parts of the building. Not every room has an outside window - only the rooms for VIP's, which is oddly similar to the situation in most office buildings.

Offices also have janitor storage rooms, elevator shafts, dining rooms, et cetera. They also have meeting rooms, labs, server rooms that can be located in the centre.

You can do a lot by varying the shape of a building. The office building that I work in is a giant H. I'm next to a window pretty much anywhere I go.

As desirable as windows are, they're also conductors of heat/cold. I'll bet that office is uncomfortable and very expensive to run.
