Key Cay and Prickly Pear/Eustatia Sound top my list as well. Didn't get to Eustatia last visit because of it being redlined. Btw - why do most charter companies redline it? Not a place to be in a northerly swell, but otherwise decently protected, plenty of room, and great holding in 10-15 feet of sand. I can see why they might not want folks navigating past Saba, but the entrance around the north side of Prickly Pear is quite straightforward.

Another one to check out is Muskmelon Bay at Guana. Great lunch stop on the way back from Anegada. Not much of a beach, but good snorkeling, the birds put on quite a show, and the scenery is spectacular. You could overnight here, but best in very settled conditions. I don't like it since the patch of sand where you can drop the hook is close to the shore and backwinding can be an issue. Would keep me up all night.

We used to like Benures as an alternative to the Bight, but I hear there are mooring balls there now.
