It depends on what you want from it, but it sounds like you want an adventure.

If I were you in this case, I'd only plan to take cc + cash + passport and some clothes. Don't overthink it.

Try to go to a hostel and stay there with other people. Just follow whatever happens (without doing too much dodgy stuff). Hostel people know how to have fun and find weird things to do. Also, be prepared not to sleep and "relax" though, so maybe only do that for half of the vacation.
