I'd suggest taking the northern route
over (i.e. up the Evvia channel and through the Northern Sporades, crossing the N Aegean to the Dardanelles via Limnos and Gokceada or Bozcaada) then coming back at the end of your cruise
via the Cyclades
. Our favourite route is from Kusadasi via Ikaria (Evdhilos), Mykonos then either Syros/Kythnos/Poros/Aegina or Tinos/Kea/Sounion/Aegina. As long as you reach the Dardanelles before late June you should avoid the worst of the meltemi and the northern route has less wind
anyway. You can find details on all the ports
en route on the World Cruising Wiki (see link at top of page).
