My son and I are supposed to leave on a cruise on Friday. My husband tested positive for covid today. I have had a headache and a scratchy throat but I tested negative this morning. I slept next to my husband last night so I am fairly certain I will eventually test positive. Do I need a positive test to cancel and get a refund? The cruise was only $600 for the 2 of us so I didn’t bother to get insurance for it. If I am denied boarding from the health questionnaire, do they refund the cruise fair?
