Rereading (or "reexperiencing") something can be very valuable. Since you already know where the destination is going to be, you get to focus your attention on more of the little details you might not have picked up on the first time through. With that said, I only occasionally do it for books because of the time commitment. I have a large list of books I want to read, and only read about 25 books a year. So if I am going to reread something, it's usually for a specific reason or I am was in a specific mood.
