Yes that is St. Thomas.
Like Lori said, it was a bit of a rocky ride out. My sister gets sea sick easily and she felt horrible, but after taking some meds and putting a cool cloth on her neck and some sprite she felt better.
The excursion was fabulous. We saw a turtle and a lot of sea life.
I'll post a couple for you.
