We visisted July 20, 2009, but just went to entrance and asked if we could turn around. For our family of four the price seemed a little high and the only thing we really wanted after sightseeing all day was just to get a picture. It would be nice if it was further along, then maybe I could see paying the price. My aunt was there a few days before and paid to get in. She thought it was worth it and said they have a lot of information about the making of it, but my family passed on this idea.
