Activity Holidays Flotilla
if you are considering sailing in the ionian where activity holidays are based i would suggest you bareboat as the sailing is wonderful not too windy and you can from island to island eyeballing if you wish.
my reservation about flotillas and this applies to most of them is that you do not get much sailing in. they tend to leave late in the morning ,sail for two or three hours then rush into a harbour to get a mooring! come back for more info if you wish
