Hello Abid, thank you for your interest in this article.. Security guards on cruise ships have very responsible jobs, so the time to actually explore the ports and destinations is quite limited. Nowadays, due to Covid-19 pandemic, it’s even more limited so I would suggest you speak to someone from Security department (I work as Shorex staff so I can’t be of much help, my comments are based on my observations). If you don’t know anyone, you can search for Facebook groups as there are so many of them, and you can seek advice over there. Have a great day!
