Yes, he was very lucky. It was not a pre-existing condition, either.
They did take him to Honolulu instead of Kona. He is well enough to text me, but he will be in the hospital for a few days.
I was on one cruise where a passenger fell down stairs, had a horrific shoulder break. We were days from anywhere, mid-Atlantic. They had a Navy ship meet us and take her off. Quite a sight.
