The Vertical Castle Town

I came all the way to this castle town to deliver a letter to the king. Turns out the royal castle is all the way at the very top. I've been climbing stairs since this morning, and I'm seriously getting tired. I've still got plenty of time before the deadline. A little break won't hurt. I asked the pretty waitress earlier, and apparently there's an inn about ten floors up from here. ...All right. I'll make it that far today. Still, I can't stop thinking about that slightly naughty place a few floors down. Should've stopped by when I had the chance. Maybe I'll go on the way back... or maybe I should go there first, before I keep climbing? I look up, and the castle where the king awaits is still a long, long way above.
