IMHO, this is one of the reasons people book excursions as opposed to just wandering around the ports. The only time we've wandered around ports were on our Norwegian/Scotland/Iceland and our Alaska cruises. We just did a Western Carib. cruise and Falmouth, Jamaica was a real eye-opener. They have a gigantic, gated and highly secured port area with shops and restaurants. If you wander beyond that, which we had to do to get our transportation for a private excursion we booked, security at the gate made darn sure we were meeting someone at that gate to accompany us in the town. I got the feeling security at the Falmouth port did not think we would be safe outside those gates. We did wander a little in Grand Cayman, however, and felt fine. We've never wandered in Nassau or Cozumel, so can't really comment on those ports. Honestly, I wouldn't do a Western Carib. cruise again. We've been to other Caribbean islands (St. Lucia, Nevis, etc.) and never felt the way we did in Falmouth. Was it educational to drive through the town and get a sense of how people live there, yes, of course. But I didn't like the fact that even the security guards didn't think we would be safe there.
