What do you mean Zanovia? If you mean Zenovia this wreck is in Cyprus and not Athens. Nevertheless there are so many divesites around Athens and trust me they DO NOT require advanced diving skills. :14:
If I remember correctly you also went to Cyprus? Natasha? Anyway with the small amount of time in Greece and the Jet lag it would have been better to spend a bit more time here and then go diving instead of arriving one day and leaving two days after on the cruise. Never mind next time !!
