I would suggest that you investigate the Sailing Holiday's flotilla schedules and dates....
Nothing worse than waiting for the wind
to pick up in the afternoon so you can sail to your next destination
, only to find that SH has taken all of the town quay spots and good moorings.
When they are on the move they are easy to spot at a distance. Like little ducks, many just motor
in a row following the flotilla lead yacht. The leader is easy to spot as it seems to always motors and has a million flags
along the backstay.
The SH base in Sivota on the botom of Lefkas is quite nice. I think you can safely go there mid week to not find them there
