Nope. In Luperon, there is a monthly anchoring fee of 15US or so which begins after your 14day fee runs out. In Samana at the government dock you can tie up there with water(and onsite fueling) for a very small daily fee, like 10 US. So if you are not anchoring, but using a government dock, possibly 50US a week is fair and square. But if you are at a private marina, I've never heard or payed the fee.
