TravelTalkOnline Forums Travel and Vacation Forums St. Maarten - St. Martin Beach recommendations on days with many cruise ships

We will be in St Maarten the first week of March. On three of the days there will be between 10,000 and 15,000 cruise passengers on island. Which beaches are recommended for busy days such as these to avoid the cruise ship crowds? We already have reservations at Anse Marcel Beach Club for one of the days. Thanks
