Figuertas is conveniently not far from Playa d'en Bossa -- so that's where I'd head for outings. Playa d'en Bossa has Bora Bora & Space, which are actually plenty to sustain someone for a while. If you take your time & don't mind the heat, you can technically walk to either from Figuertas.
Space is just a little further than Bora Bora.
If you go in the opposite direction -- you'll be in Ibiza town -- which has loads of little bars (and Pacha and El Divino)... but for flat-out-ease and all day sessions, Bora Bora is dead easy.
