Hi, I'm doing a working trip on the MSC Divina. We'll be in Grand Turk on April 5 and I'm thinking about diving. I pretty experienced but I don't expect much more than a shore excursion type (cattle boat) experience but if I'm there I might as well dive. Wondering if it's worth bringing a minimum kit (prefer using my own stuff). Would a 2 mil shorty be enough exposure protection?
