Although a lot of this information can be found on the Disney website, it's certainly handy. I did not read the chapters that weren't related to our particular situation, cruise destination, ship, and port adventures. I discovered some hints and information I wasn't aware of, and of particular value to me, were the ratings of the shows on board. I have a tendency to think I have to take advantage of everything offered, so it was nice to know that perhaps there are a few things it might be OK to skip. I was hoping for a little more in-depth information regarding port adventures, however, there was enough regarding our destination that what I read actually changed my mind regarding what port adventure we chose. I think it was worth the purchase.
