I purchased one of the Disney Discount Books.  It advertised being able to save up to 50% off of the park hopper tickets (among other discounts while in Orlando).  My only reason to purchase the guide was for the ticket discount.  You can bet Disney has caught on to this trick.  The guide that I purchased wants you to really stretch the truth (lie) to get your discount, gee, they don't mention that in their description.  I tried 3 different times to purchase my discount tickets without success.  My tickets not only cost me full price, but also the 7.99 for the so called discount guide.  I left honest feedback that the seller did not appreciate.  In return he called me a liar and a loser, not only did I report him to ebay but also to Disney, (and they contacted me by phone).  Don't waste your money!!!
