Santorini to Athens: the ferries from the Santorini to Athens stop working by Oct 31 (but there are few connections in Oct). The 9:30 pm ferry to Athens takes 7 h 20 min to get to Athens.
I d say Athens, Mykonos, Santorini 3 days each and 5 days in Crete. 1)Athens has lots to see but is a big city and in the summer islands are better. 2)Santorini and Mykonos are beautiful but very small and very busy islands, so 3 days on each should be more than enough. 3)Crete combines island with big city.
