Is Merzouga good for photography? What are the best photo spots?

Outstanding — the great dune behind the camps at golden hour, Hassi Labied’s palm lines, Dayet Srji’s mirror at dawn and the star field after moonset.

The light does half the work: shoot the hour after sunrise and before sunset and almost nothing can go wrong. Bring a lens cloth, skip the lens changes in wind, and stay for blue hour when the dunes turn violet.
