This Palmer House room guide thread:

and my own thread asking about Drake Chicago hotel rooms:

got me thinking about this subject:

Has anyone ever seen a room guide/map to Hilton Hotel rooms? Something in the way that seatguru.com has maps of different airline flights.

I've seen a bunch of threads where people mention what rooms they had and rated them with descriptions. Novel idea, but too hard to keep track.

It seems even more important now that Hilton has instituted the e-checkin process. It would be so much easier for people to use the system if they had a map of the hotel detailing the location and description of each room.

Anyone seen anything like this or have an idea on how to start one? Would be a great resource.
