What was the basis for mandating that? One of the islands demanding it, Explorer Ventures, or what?
On a mid.-July family cruise, we had to have a proctored COVID-19 negative test result within 2 days of the cruise to board, and it's nerve-wracking to plan something like that, do the research, make the plans and pay the costs...then not know whether you'll get to go till 2 days before. And we were fully vaccinated and boosted!
How many total dives were you guys offered this trip? People picking liveaboards are often after a high dive count.
I keep coming back to this point. The few sporadic reports on St. Martin/Sint Maarten we get on ScubaBoard do, IIRC, report pretty good general Caribbean diving with the added bonus of Caribbean reef shark sightings on some dives. The rare mention of St. Kitts diving (which I only recall coming in trip reports on this boat, where Saba diving is more the highlight) tends to portray pretty good diving but nothing all that special, again IIRC.
What I'm saying in a round about way is, I'd like to know if the diving by St. Kitts is better than the diving by St. Martin/Sint Maarten or not.
Neither St. Kitts or St. Martin/Sint Maarten seems to be the subject of land-based dive trip reports where someone goes for a week mainly just to dive. Unlike Cozumel, Roatan, Belize, Curacao, etc...
