Hi Tom!
This helps a lot! Fortunately(or unfortunately depending on how you look at it), it is a pretty simple shoot. Nothing on the water. It's a doc about a wedding planner. It sounds like it's mostly indoor stuff, with an event at a fancy place overlooking the ocean. No beach or anything. Nerves went at ease when I was told this.
However, I definitely appreciate all the advice, and I will definitely prepare accordingly, especially clothing wise because you never know. I am definitely stoked to listen and learn about the culture of the island.
