It sounds like you have a previous version??
I only got this latest version, and for a family that visits about every 6 months, which you seem to visit quite often too, we really enjoy this book at home and at the hotel (after going to the park). We have fun with the pictures and talk about the ride. We liked it so much, we've just ordered the Lost Adventures book by them... My DS loves looking at a picture and saying where it is... (i.e. they show pictures of diff clocks throughout the world and you have to "find" it) Anyway, we really liked this book.
