Looking for group wisdom please!

We are currently in the BVI (Diamond Cay) and are thinking of sailing to Great Harbor on Peter island tomorrow since we have never been there. NOAA predicts a 4 ft north swell. The Moorings chart briefer said that Peter is bad in a north swell but others seem to disagree. So should we go or should we default to Norman (which everyone seems to agree is excellent)?

Thanks in advance.
