I did a ship tour that combined the rain forest with the falls. I think it was
this one, or the equivalent. The port was a little scary with people yelling in all directions. They kept us in a group and it was okay from a safety standpoint. This was several years back though before they added more security at the port area, and the Margaritaville beach. I have to agree with not wondering very far if at all from the port facility.
