There was a big sign when we got there to check in if you were a photographer. We couldn't really find anyone to talk to in the gift shop, so we just wandered around and took pictures. Jailtime to come, I guess. We've gone a couple of times now and there is always a professional photoshoot going on, so maybe they just meant the professionals. It looked like there was a tour of some kind, but we still couldn't find anyone to get more information, so we just wandered. It was such a beautiful day both times we were there, which made for some awesome pictures.
For such a short drive from Vegas, it's a day trip that everyone should take at least once.
