For 16JD I would expect much more, the beach is not very nice. There are some seats and metal frames (tables?) on the beach which are very old and dirty. At the time that I went, which was first thing in the morning, the showers and changing rooms were dirty.
Overall, the beach is functional, mine was a flying visit between Aqaba and the Israeli border, so it got the job done. However, if you find or hear about a better beach then by all means go to that one.
