I also think 5.13 (The Song Remains the Same) and 5.18 (Point of No Return) also use this floor plan but I can't get a good enough cap of it.
I just love that they turn the plan around to mix it up a bit. I scanned through S1-3 and couldn't find this plan used there. They used it 5 times in S4. It appears again in S5, S6 and S7. The hotel layout on 7.05 us slightly different but it looks like they've simply made a couple of trims to the original. :)
It's TOTALLY geeky and a completely useless find but it makes me smile. I love the idea that the set designers had a standard floorplan and just changed the name on the graphic.
