I apologize if this question has already been asked. I searched and could not find an answer.

I would like to visit the set if possible. I live on Oahu and my father is visiting me. He is a HUGE fan of the show. He hasn't been this into a show since Star Trek. Okay, maybe American Idol. He is a disabled veteran and this is his first, and probably last, visit to the islands and I would like to take him to visit the set. Are there any tours given? Where can I find this information?
