I will be taking my 3 nephews to Knoebel's when I visit in July. I am trying to decide whether to go POP ($37 each including coasters) or buy ticket books. My question is: What are the value on the tickets in the books? Some rides are .75 & some $1.25. Seems like the tickets must have some strange values. Does the ride give "change" so to speak? I guess I don't understand how it works. The only time I remember using ticket books for rides was at the fair growing up and then each ride was either 1 or 2 tickets. Not these strange $ amounts. I am thinking it would be more economically to buy the books especially since we would be going during the week and will get a discount. 1 of the boys will not go on the bigger rides The bargain night doesn't work for us as they live almost 2 hours away.
