Its not that it is dangerous or anything, so to answer your question, sure you can take her off the ship. BUT, I think of Freeport as the very definition of "Tourist Trap". The ship pulls up, everyone gets off and you are forced to take a $15 cab ride (That's in 1990 dollars BTW) across the island where they drop you off in the shopping village. Which is all there was to do when we went. We found a beach by the village and relaxed. But we felt like we were being taken from the moment the ship pulled in.
If you want something to do, take the beach break tour. Its your best bet.
