The beach is definitely different..but in the end that was not as huge a concern as we sometimes imagine it could be.
We were really pleasantly surprised by CTI (and Ochos Rios). The staff and resort were great. Especially the staff. The food seemed to be Chef Spath all the way, and thus was very similar in taste and quality to CSA. In fact I thought the buffets had a slight edge over the ones at CSA as far as quality. I will happily go back to CTI in the future. It's a great place.
