Nah, I was actually on the wrong map altogether - I missed that the "scroll to the bottom" was meant for the initial page, clicked on the link and then on the top map, and then scrolled. Which doesn't help because the top map has much less detail.

But the way people were talking, I thought it was going to be a case of "It's the second room on the 26th floor" (joke being the hotel only goes up to 25) or such. Not "Yes, it's marked on the map in a perfectly reasonable fashion, indistinguishable from all the other rooms that actually exist."
