Some of us will stay a bit longer after the official part of the MegaDo has concluded. So let's start collecting some ideas and maybe organise groups according to interests. I myself will have the whole of Saturday and will need to leave in the late morning of Sunday for my 13:45 flight back to ZRH. It's my first time in Athens so I am interested in everything. Definitely want to see the Acropolis and maybe do some interesting not so touristy stuff the rest of Saturday.
