Koper, Izola and Piran have nice old town centres but Portoroz is more modern with big beach and road avenue a bit away. In Portoroz you will find many bars where you can drink beer, wine, coctails and of course other drinks. Alaya is one of the most popular for night life. In Portoroz you will not find some really special cultural-historical sights but at least from distance it is worth to see Kempinski Palace Hotel. For music and other events you should visti Portoroz Auditorium. The most interesting town on the beach Piran is not far away so you can even walk from Portoroz to Piran almost all the way along the sea.
