I have to share this. My wife and I did a third party excursion through a company called Southshore Excursions. We did a Zipline tour and it was AWESOME! We can highly recommend. It was only about $52 and worth every penny. The directions weren't 100% precise on where to meet, but you literally need to leave the Disney-like facility that carnival obviously looked like they fronted, walk up the hill and over and you will see a lot of locals. I could see how it could be a little intimidating, but it was well worth it. Let me know if you need any information about it.
