A friend of mine just got back from Jamaica and warned me about the Chukka zip line excurtion she took, [booked independantly not with cruise ship] she said they hiked more than zip lined...but said others rode a truck or something up to the zip lines? She said not to miss Dunn River falls, especially if it's your first trip to Jamaica, like ours will be. I hadn't planned on doing DRF, but instead was going with RCI's zip line and kayak trip? I might have to re-think that early decision...plus if I book something independantly I'd save a fortune. The DH wants zip lines and Kayaking though...? Anyone know an indep. tour that does both? most I've seen are not put together but are parts of other excursions.
