I had a great time. I also had a minor panic attack at the "rappel" portion. I imagined the rappelling to be straight down and you kinda just continuous glide down. In actuality, its on a decline, and you will go across a river/waterfall (which is pretty cool) and you have to feed the rope yourself which can be a bit jerky especially if you're small. I did it and was fine, but if you are going to become completely incapacitated by the sight and idea of this part then skip it. It was worth it for me in the end and the guides were very helpful and nice.
An added bonus is that after you do your tour you have access to the whole property so I recommend doing one of the earlier tours so you can take advantage.More
