Hi Wendi,
The offers that you use from the Orlando Entertainment book are going to be dependent on what you'll be doing and where you'll be going.
There's car rental discounts if you'll be renting a car. I'm partial to National because I'm an Emerald Aisle member (let's me skip the counter) and there are several coupons for $20 off a weekly rental, free one- & two-car class upgrades, free weekend day, etc. That alone could save you the cost of the book.
Then there are entertainment coupons like the Arabian Nights or Medieval Times Dinner Theaters. You can get discounts on miniature golf, Magical Midway, Gatorland, Sky Venture, the Titanic Exhibit and Wonder Works.
There are coupons for fast food and fine dining.
The problems with using the book arise when you are staying onsite and have no access to transportation offsite. Then, you're pretty limited to whatever is offered within the confines of Disney property. In that case, you can get one free enrtrée with a paid entrée at Baskerville's in the Grosvenor (a DtD-area hotel) or Disney's AllStar Café in the WWoS by showing your card.
You can also get discounts on Universal Tcickets, Sea World Tickets and Busch Gardens Tickets, but they are not as good as the discounts offered by ticketbrokers.
