We are going on the Allure in a couple weeks and are new to cruising. I have read about a couple medical emergencies where ships have had to go back to ports to evacuate the a patient therefore some ports have had to be skipped or shortened. I am 100% for a person's medical needs as top priority so just curious why they don't air evacuate the person needing medical care with a helicopter or call in the cost guard? It seems like it would be a lot faster.
