Is there anything out there like FlightMemory.com for hotels?

I've been traveling for business for about 2 years now (first job out of college) and I found FlightMemory.com about 6 months ago. I was able to go through my travel requests and find all of my old flight info and I update my new flight info after every trip.

I would love to find a similar (identical?) tool for hotels. It would be fairly easy to dig out my old stay info since 95% have been with HHonors. It would be neat to generate a push-pin map similar to the route map as well as log room number info, restaurant info, upgrade success, ect.

Anyone know of such a tool? If not maybe I can make a little money setting up HotelMemory.com!
