Ok, true confessions....I'm a physician. I met one of the two ship's doctors in the atrium one evening. She was wonderful...described her work schedule, etc, and invited me to tour the medical facility. The "infirmary" is really quite impressive. They have a small ICU area, and are equipped to handle the vast majority of issues they are likely to encounter. They are essentially like a well equipped emergency room, plus handling the medical needs of the crew...and having the facilities of a very small hospital "just in case." It is not their desire to provide any long term care, but they are equipped to manage things well until the next port of call or the return to Port Canaveral. Most of the crew are fairly young and healthy...but some are away from home for the first time, and all are subject to the same minor illnesses that may affect us all. A big issue is the possibility of an ill crew member infecting passengers.
The nursing staff that I met on the tour was also very friendly. I didn't go into detail as to their experience, but they seemed competent and knowlegeable as I was shown around. They were very willing to answer my questions, etc.
The physicians are not employed by Disney...they are hired by an outside service and assigned to
DCL, of course meeting the standards that Disney requires. Disney actually has more stringent requirements than many cruise lines, and isn't interested in having people who want to play cruise doc for a few months or a year...they are interested in fully trained docs who want to do this as "permanent" employment. I don't know who actually employs the nursing staff.
So...guess this is a positive experience....yes, everyone is a bit hyper about the Norwalk issue. Again, their main idea is to protect the largest number of passengers and to keep the medical aspects of the cruise running as smoothly as possible.
