THIS is what I'm here for. Knobbgb giving me the clue I couldn't ferret out myself with the island hopping info. THANK YOU!

I want very much to visit some of the lesser islands in a round-ish-robin but I couldn't see how by working the schedule on my own. The Kasos-Karpathos clue showed me that I can string some longer trips (using tickets of three legs each) to visit with 6-23 hours between flights--long enough to leave the airport for a few/couple of hours and look around (even if only nearby or on foot) before hitting the next place. I'm still going to be mostly an ATH/HER/CHQ/SKG kinda guy, but always pivoting off ATH to the lesser places sounded dreadful. Cheers!
