Go back to Turkey.
Go back to Kas.
We drove back to Antalya with enough time to get the car nicely detailed before returning it. You can beat the shit out of your rental so long as you give it a little cleaning before turning it in; a lesson learned the hard way some years earlier in Oman. We flew back to Istanbul with a day left over for sightseeing. The usual sights were interesting though access was limited for variety of reasons. Though the highlight by far was a visit to the baklava bakery reputed to be the best in the city (if not the country). What Hong Kong did to us in terms of dim sum, Istanbul did the same with baklava. Truly a religious experience and one that has ruined us.
