First...the guides were awesome, it was safe, and our daughters fully enjoyed the whole experience. we loved being able to hike the trail to watch them on most of the lines as well. However, we saw the option to rent go pro's from the website and when we inquired about them, they were not available but were told they still had the sim cards for them if we wanted to use our own. Wasn't really thrilled with that answer since we clearly didn't have our own if we were asking to rent them. Also, even though our daughters loved the zip line, the advertising was so similar to others that we thought they were getting a more advanced course then this one. Partially our fault there.
