Pretty sure you are towards the bridge from where Azure is located. I have walked that area many times and only recall seeing sea urchins very near the bridge. The beach can change with the conditions and there are usually rocks/boulders under a lot of the sand in many areas.

If you have not committed, you might check out The Horny Toad. Beach is nice and it is very near Azure and I know the beach is nice in that area. No pool and no TV in the rooms but a nice place that is very comfortable.
