The state has cut-back on personnel. To accomodate the number of tourists there are now just 3 tours. $25 each you buy one down at the visitor's center (includes the movie on the history and the construction of the castle) and you get bussed up to the castle and you wander the grounds on your own! (great for photography) Then you can buy the additional 2 tours ($25 each) up at the castle if you want them (or your feet can take it). I think this system is pretty slick and very practical!
