I had this book recommended to me - there are several editions, and apparently the Orlando one has lots of savings in it that are miles better than the savings offered in the free papers people usually pick up when they arrive:

The 2007 Entertainment® Book - Great Savings on Dining, Shopping, Travel, Attractions, Movie Tickets & More!

At the moment its expensive, but often they reduce the price for a limited time, and if you mail order it when its reduced you'll make the money you paid back, and then some, very very quickly.
