It sounds like the MSC cruises in the Med have been uneventful COVID-wise. I have to be honest -- I thought 70% capacity was too high, but I haven't seen any news stories about outbreaks. Ponant has had similar success over the last couple of months (albeit with much smaller ships)...

Please share more (how many/which ships, resumption dates, etc) when you can!
I don't yet know how widespread it is, but a few people have had contracts canceled that were heading over next month. Rising covid numbers were cited as the reason for the cancellation. I do not know what this means for the the return date of (dcl) cruising, but it can't be good.
