I think most any place that appeals to you will prob let u use the property if u buy a drink or some food....
I have swam from Samsara, Blue Cave Castle, Negril Escape, Tensing Penn, Catcha, and Xtabi, with Xtabi being our favorite....the different levels, the caves, and the sandy entrance from the one cave make it our fav.....not counting that it was our 1st place we discovered on the cliffs to hang out....
