I haven't been on any of those, just one in Jamaica. I'm trying to figure how to build one in our back yard.
I don't know anything about your 3 choices, sorry.
Did you look on youtube for ziplines? You might get lucky & find clips of the ones you are interested in.
My DDs went zip lining in St Lucia and had a wonderful time. The equipment was great and runs from stand to stand were beautiful. The weight limit was also up to 300 pounds, so the equipment was very sturdy. Have a great time on your cruise.
well, my choice for the best zipline is not on your list either. It is the Dragons Breath in Labadee.
here is a link to an album with phots of it. scroll down to the bottom to see where the photos of this event starts, then click on the 2nd page for more.
