There has been a few reports out of Europe of "closed loop" domestic" cruising". Eg: Sailing around Norway... for Norway residents... Sailing around France... for French residents and so on. Goal is that no one would fly in and these cruises would be for "locals" only, and from areas with low COVID infection rates. There has been some rumblings that Florida ports may focus at first on the "drive-in" market and this could be one of the reason why some cruise lines are quietly dropping targeted cruising offers outside of the "local" market (eg:
DCL currently has no special offers for Canadians, but still has Florida and Military)
