All guests must ensure that they are medically and physically fit for travel. The Centers for Disease Control (CDC) and the World Health Organization (WHO) provide guidelines as to which vaccinations are required in each country. In many cases inoculations are recommended, but in some circumstances, they are required. We recommend that you check with your health care professional or a Travel Medicine Specialist certified by the WHO for guidance. Other informational resources can be accessed on the Centers for Disease Control and Prevention traveler's health website or by calling toll-free (877) FYI-TRIP and on the World Health Organization website.
