There are a few people (even here on FT) that fly in, and fly out on the same plane, and count it as visiting a country - to each their own.

I personally dont see a point in that.

But when I take the boat over to Anguilla for the day later this summer, and rent a car to spend a 9 hour layover in Antigua - I will certainly count those as a visit. Likewise, if I was to spend a few hours onshore from a cruise, but not if I just stayed on the ship in that port.

Everyone has a different definition.
