I got this reply from DC a couple of days ago:

Private cabanas can be reserved no earlier than 3 weeks in advance. They include a shaded structure, table and chairs, lounge chairs, and a beverage refrigerator all tucked within the lush landscaping. They are $175 per group of six ($186.38 including tax), and can be added to your reservation by contacting the Reservations Center at 1-877-4DISCOVERY or 00 800 33 44 1818 from the U.K. or 1-407-370-1280 from other international countries.

Hope this is useful.
