Deb,
We went on the Beach Snorkel Excursion, which is how we ended up on that beach.
I think this is the URL to my report about our day at Costa Maya.

We did hang out at the pool for a couple of hours, but did not go to or see the port beach. It looked VERY rocky from what I could see. I think there's sandier beaches over by the actual village.
