My wife went on this as part of our adventure away from the kids. We went on a Tuesday afternoon with just us and another couple. Our guides, Jesse and Avery, were friendly and knowledgeable.
I felt encouraged to see the guides take safety seriously. You go up to 50 mph on the fastest line. It's not hard to imagine blowing out your knees or doing serious damage, not to mention falling from 100 ft up. They did a great job making sure that we were tethered at all times and that the lines were clear before anyone went.
Overall it's a very fair value. We paid $64 per adult and our small group of 4 finished in 75 mins. I recommend it to anyone in reasonable physical condition that won't be completely paralyzed by fear of heights. Nobody gets off of a zip line without grinning ear to ear.
