What an awesome experience! My husband, sister, daughter-in-law and grandson did the 7-Line Maui Zipline Tour a couple of months ago while on vacation. I don't remember the names of our guides, but they were so amazing with my 8 year old grandson- interacting and paying special attention to him to be sure he got the most out of the experience.
I expected fun, but this place is so much more! It was a true WWII US Marine Training camp. I had no idea, as I booked through an activity booking place. There was a small outdoor museum in a huge tent that had a couple of old war planes and jeeps. Each line platform had historic information for reading while waiting your turn and a couple had amazing ocean views. There was a photographer, capturing great shots for sale at the end of the tour- prices were quite reasonable, too! As if all of that weren't enough, there are even a couple of friendly dogs roaming around and a cat in the gift shop!
Definitely a must do adventure while on the island!
