Really good. Fascinating trip around Las Vegas learning about it's history and visiting some very interesting places. I would have like to clarify a few things that aren't made clear on the website. This is not a walking tour, the majority of the tour is on a small 'mini' bus with the tour guide and there is a little bit of walking to and from the various haunted sites but nothing major. Don't listen to anything saying about not taking photos. I didn't bother taking my digital camera thinking that I wouldn't be able to use it. When the tour guide took us to our first haunted stop he said 'I hope you've brought your cameras because previous guests have caught orbs and other such phenomena', and then showed us some photos. So my recommendation is bring your digital camera with you and snap away, you never know what you might take.
Highly recommended if you like hearing ghost stories, or, if like me, a huge fan of Most Haunted.
