The Mariner was advised 1 hour before departure from Bora Bora that American Samoa is banning all cruise ship visits through the end of March due to Corona Virus concerns. We will also bypass Samoa (a different country) and sail for 4 days to Fiji where we hope to get a berth a day early. Right after the announcement was made and just before the anchor was raised a generator failure put the ship in the dark for a few minutes. No lights, toilets or internet. After a ½ hour delay for Engineering to check out the systems, we set sail.
