indonesia or sri lanka?

hi everyone,

i am really indecisive about which one of these i should go to in july. if someone here has been to both, please let me know which one you would recommend most and why! :)

we like nice beaches and nightlife but also nature, culture and wildlife. i think both countries offer all of this which is why we are in a dilemma. really need to hear some experiences of others to decide!

edit: with indonesia we’re focusing more on bali and places nearby that can be reached by ferry because we rather not take flights to get around, since we are only going for 2 weeks.
