I live in the non-touristy side of the island - Sta Eulalia where the beaches still get packed but there are some very quiet ones like Aigues Blancas (White water) the trouble is you want it all in one fell swoop and you will need a car for all this. The nice quiet areas do not have good night life which is why they are quiet - Es Cana is quiet busy although very small - with a car its in reach of everywhere. There is nightlife but its bars not clubs - the same with Sta Eulalia. Wish you luck
