As best as I remember, I recall the Greece restrictions being applicable for most (if not all) cruises we've ever taken. Aside from water (we even had to ditch the coffee), nothing can be taken ashore. (Saw the dog sniff someone out in Cozumel a couple of months ago)
Yeah, I pointed that out a couple of days ago, but someone got their feelings hurt and the censors jumped in. Maybe they wanted to get this out there to mention the use of Ivermectin (the most effective sure) and try to promote its use for something it was never demonstrated useful for---Covid-19.
