We've day-anchored at Drakes. Not sure I would overnight there unless the wind was on the light side of normal. Prickly Pear is a good overnight spot. There used to be balls there. Anchoring is good although the sand is hard in spots....make sure you have plenty of scope as the slope is not in your favor under normal conditions. Our fave spot to overnight (for seclusion) is the other side of PP island. There are two beautiful white sand beaches (usually deserted) facing NNE but in the lee of Eustatia I. Short tender ride across to the reef WNW of Eustatia for some great snorkeling.
