Boarding will be denied to any person with a severe, chronic medical condition, including those specified by the CDC. Guests of all ages will be screened prior to boarding, regarding underlying health issues that may prevent them from sailing. My question is if I am a type II diabetic that is healthy and only take oral medication will I be denied boarding for my cruise? I don't want to show up and be asked if I'm diabetic and be denied boarding. There are many diabetics who exercise, don't smoke and control their sugar levels and are healthier than non-diabetics.
