I ordered my book (2002) from my daughter's elementary for $25 this last September. It is a local discount book that comes with a card that is honored all over the US.
BUT, if you join the Disney Club, you automatically have the entertainment discount available to you, since the Disney Club Card has the entertainment logo on the bottom of the card. You would save the cost of buying two cards then. I f you were looking for a hotel that honors the entertainment discount, you could call the hotel and just ask what their entertainment rate is, and they will let you know if they honor the discount.
Otherwise, the entertainment book lists a lot of hotels and restaurants, etc that honor the discount.
You can buy the book at major bookstores too. Saw them at Barnes and Noble and Waldenbooks.
Or log onto entertainment. com and see when 2003 books would be available.
Just a note, the hotel I stayed at, CI&S at Calypso Cay Way was not listed in my book as a member, but when I called 800 number for reservations, I asked and they said they were. I got a great hotel for 39.50 per night.
