I've used the Entertainment Book for Orlando every time we've gone to Orlando. I usually buy it in mid-summer just before the trip. The book is usually discounted and/or has free shipping/handling and on a few occasions I've gotten a 2nd book for just $5 more (Orlando or any other city).
The last time, I went down to Orlando, I had 2 Orlando books. If you read the "Rules of Use" in the back of the book, you can actually use more than one coupon per party. Here is the actual quote from the book: "5. Dining Discount Details....Only one coupon/membership card may be used for every two people, UP TO a maximum of three coupons/membership cards per party, and seperate checks are not allowed." So, if you are a party of FOUR, and you are ordering FOUR adult-size meals (child meals excluded), you could use two coupons in order to get two FREE meals. It is possible, because I HAVE used two coupons. Apparently not too many are aware of this, as I had to point it out to the waiter at one of the restaurants.
