Yes - each Passporter has folders in the back that you can fill with your confirmation from your resort, your PS's, your game plan, etc. I also put envelopes in with the cash for our towncar services. Everything neat and tidy!
One of the best features of this book, IMO, is that the authors have the times that Disney restaurants are open (example - 11:30-3:00 for lunch and 5:00 til park closing for dinner). I use this all the time, since we tend to do PS's at odd times to avoid crowds!
