There is an app I love called TripIt. I have it on my iPhone (heard about it from someone on these boards). You can give the app permission to access your emails so it can look through it for any travel related documents (flight reservations, dining reservations, hotel reservations, concert tickets, etc). It takes all that information and puts a little itinerary together for you, including all the confirmation numbers. If you don't like the idea of giving the app permission to access your email, you can forward everything you want included in your TripIt itinerary to an address they provide (plans@tripit or something). You can go in and edit any of the itinerary items, add stuff (I added things like Wishes and included info on where we want to be at what time). The app is free, but you can upgrade for more features. I really enjoy the app and it is definitely useful for keeping track of your ADRs. Definitely check it out!
