I would give it a zero, if possible. Five minutes into the swim, a fellow cruise passenger was not feeling well and they sounded a horn signaling that we should all return to the boat. From that moment onward, the sheer incompetence a lack of preparedness of the local folks to deal with a situation like this were more than obvious. It took forever to reassemble all passengers (who could have been left with other ships in that area), there was no emergency plan, and when we got back to port there was no ambulance waiting (this part really shocked me). Perhaps as a result of all these factors (or with their contribution), the gentleman did not survive.
