we just got back from our trip to AC and having been to other places in the carribbean, AC is not a nice beach destination for swimming.. it is not a swimming from the shore place period. not to say we did not love it, we did, but not for the beaches but for the snorkeling and such. the beaches in town are packed and small. if you traveling without children, check out the places north where the sand is very nice and the beach larger with no traffic on it. we really enjoyed our trip however and had a blast.
