Forget all those reports in the British tabloids about the Princess of Wales and her new boyfriend in the Caribbean. Diana is in the Caribbean — at the K Club in Barbuda for the second time in three months — but she’s traveling with her two sons, Princes William and Harry. The Princess has also brought her sister’s daughter, a secretary and three security guards. That’s three more than Di had with her on her last trip, when the British government cavalierly told the local authorities to provide any protection they felt necessary. Things obviously change when you’re traveling with the heir and his spare. The royals — and their guards — are said to be having a rip-roaring time and will be at the club until Saturday.
