I am planning a trip to Mykonos and Santorini for early Oct, the 4th-13th. I am now concerned about weather and level of activity. I am not looking for a wild, crazy party atmosphere, but I am hoping for some active nightlife. Mykonos would be Oct 4-7 and Santorini Oct 7-11, then back to Athens. Does anyone have any input on either the weather or level of activity to expect at that time of year? Thanks so much for any input.

Days will be sunny with some wind and nights will be chilly and windy. There will still be lots of people visiting until the end of October.
