Hi, this is Chris, StationStops blogger and author of StationStops for iPhone. Thanks for the mention. I just wanted to point out that StationStops is all one word - might be hard to search for if you split it.
BTW, I am not a Metro-North conductor or affiliated with MTA. I think you might be thinking of the awesome Metro-North conductor blog DERAILED: http://bobbyderailed.blogspot.com/
Again, thanks for the mention Chris I'm glad you like the app.
Reading this post I wanted to know what turndown service was about too, so I googled it.
I think the turndown and the chocolate are just to get them in the room and replenish the toiletries and towels if you have used them that morning - this avoids people calling the rest of the night for this stuff so they can pare down the housekeeping staff for the evening.
I think its also the easiest tip money in the hotel housekeeping business.
