Dude, it's not just the five lights. It's a ride which lasts a whole minute. To go down one deck? Forget it. It's an error. Like I said, we'll never agree, so let's just agree to disagree, and move on. OK??
P.S. What are guest quarters doing on deck two anyway? That's rhetorical by the way, so please don't answer. Kirk was not being euphemistic about giving her quarters.
Port-side VIP cabin (one of two) on Deck 2...
This is one of only a few spots in the primary hull which have windows... which is sort of an expectation for a VIP cabin.
Essentially, this is the "admiral's quarters" which Scotty compared basic quarters on the 1701-D to.
That's how I view it. Of course, part of that is because this space is really unsuitable for any other use, due to low headroom. A couch, a big bed... those can go underneath that sloped ceiling, right next to those windows, and it all makes sense, though.
