This cabanas are along the walkway across from the Magic Carpet, a rather busy route to the Mast Grill and Solarium. I did see folks being served drinks, blankets, etc but usually they were empty. I believe there is a more complete description of what is included in the plan my trip section of the website. Magic Carpet was used as a bar area when weather permitted on our cruise, not sure if you can order food but never saw it set up as a dining venue.
