Hi - love the answers and all the enthusiasm, which I feel too. The days before going to St Maarten feel to me like the days leading up to Christmas as a kid.
I especially like the answers referring to sand gravity. Not to get all metaphysical on you, but I think what the term means is something like this. It's not what you did or where you went, but who you were with and did you have a good time. So to me that means put the emphasis on enjoying the moment, not chasing the next cool place.
That said, I would explore Orient, Maho and Grand Case, and from there on go back to your favorite of the three, repeatedly.
Have a great vacation.
