My parents had visited this "tourist trap" back in the 70's before I was born. I remembered seeing the photos in the photo album and was always interested. So, this year we took our kids and everyone had a good time. The tour only lasted about 15-20 minutes, but the photos will be a classic in our photo album for years to come. Be sure to "volunteer" to take part in the "illusions" so you can see it for yourself. Most adults can figure out the illusions but the kids were baffled beyond belief! A must see!
