Not sure why you haven't heard of a norovirus outbreak on
DCL but it happens all the time. DCL will shut down the buffet self service and will be CM served only. The drink stations will be manned by CMs from 7am to midnight. There will be more people wiping down railings and touch surfaces. I've been on several cruises with noro outbreaks. The last day they become less stringent as you are leaving and taking your germs with you.
