This just goes to prove that there are as many opinions as there are people. Having been to both Grand Cayman and Costa Maya we always found good safe things to do.
As for seeing armed guards around the port, this is one person's armed fortress and another person secure port area, just like any area around an airport or port facility in the USA - there are armed police and security guards everywhere.
At Grand Cayman the turtle farm and the dolphin experience right across the street from each other are really fun, and you can just take a taxi to and from - you do not have to do the DCL excursion which is much more expensive.
We had a great shopping experience in Costa Maya, much less pressure and better pricing than the other ports. And the locals were awesome in their hospitality!
So that said to each their own - there is no reason to disagree - just state your opinion and let others state theirs and then everyone gets good information from a varied view point!
