We visited Sta Monica Beach Club last year, walk in fee 500p and you can use 400p for food and drinks. Good pools and also a beach there. Sea View Beach Resort near Sibulan have a small pool and a rather good beach. Walk in price 300p including food like a snitzel. More far away is Thalatta Dive resort, we paid only 100p for using the very nice pool when we eat in the restaurant. No good beach there but ok for a walk or swim. You vill find them in Google Maps.
