The books are currently $29.00 per person and are offered by the vacation planners who "work" the pass sales lines. These books can be purchased at any of the pass sales windows at both parks. Prices vary since this is an experimental/test program only - prices have ranged from $25 to $30 per person.
What are they? Basically, think of them as a book of Express tickets for every attraction that offers Express that can be used whenever you would like.
For example, at IOA the book consists of 15 coupons (one for each attraction). The coupons are dated (in other words, you HAVE to use it that specific day) and the attraction logo appears at the top (again, in other words you can't try to pass an unused Storm Force at the Hulk). Each coupon allows one guest to use the Express queue at each attraction only once at their convenience.
The benefit? You never have to worry about attractions running out of Express tickets or planning your day. Walk up to the attraction whenever you want and get into the Express line.
The cost? Well, since each booklet is only good for one person - a family of four will be paying almost $120 for this program. Also, you can only do this once at each attraction. Obviously, if you are staying in one of the on-site resorts - there is no reason for you to purchase this booklet. No, there are no other coupons (other than the Express tickets) in the booklet - but that's a great idea!
Why do it? Because both USF and IOA only have a few hundred of these (less than 300) available each day and they are practically selling out!!!!! It's amazing how many people are snatching these things up as quick as they can!!!!
So, to answer your question, yes - these do exist. It's currently an "experimental" program only and unadvertised.
