Part of this small island is Dutch, the other part is French. When you cross the "border" there's no passport check or anything. Both my taxi drivers noted that the US dollar is the de facto currency, at least on the Dutch side; only government workers are still paid in (Netherlands Antilles) guilders. In fact, no one I asked had any guilders on them that I could trade for!
I'd go back and visit any of the islands again, but St. Maarten will be the first on the list. In addition to its just being beautiful, there's world-famous Maho Beach! Sadly, when we got there we'd just missed a 747, but we did get a fantastic experience!

Hanging out at Maho Beach is the most fun you can ever have for free :-)
