OP, as jory mentioned, yep!
I hear that NZ and Australia have ent books too, and they work as well.
pigby....I'm not sure that the coupons in the OC book are good for places right near the resort. If you have a car that might work, but I would really check out the entertainment dot com site (you can join the site and look around withOUT owning a book!) to find the exact locations of places accepting the coupons in Anaheim.
But you don't have to buy the OC book at all. For those coming from places that don't have the books, if you're going to buy a book, just buy the cheapest book. I've noticed that the Arkansas book is fairly inexpensive compared to others.
And then there's the aspect of being able to just buy the card from ebay.
