I'm planning a trip for this coming September for Rhodes, Kos, Patmos and Corfu. Despite the fact that almost nobody on this forum seems to ask about those islands, I know they are popular, especially with 'package tours' from northern Europe. So I planned on September thinking they would be less crowded. But now I'm starting to worry I may be restricted by reduced schedules in terms of things like ferries and flights. For example I see that the last flight of the season from Paris to Rhodes on Easyjet is August 29. I can make that work and it looks like I can get between Kos and Italy the third week. I know ferry schedules for next year are not out yet.
So my question is - is it still 'high season' in terms of everything open, frequent ferries, etc.? What about crowds?
My plan is fly into Rhodes and base there about 6 nights, doing day trips to Symi and Chalki. Then move to Kos for a few days, then to Patmos for a couple days and back to Kos so I can fly to Corfu. I don't see any direct flights but I do see some on Agean with a stopover in Athens. Then about a week on Corfu. I was thinking of a day trip or an overnight side trip to Albania during that week. Does that plan sound doable? reasonable?
