First, I'm not worried about the museums, banks or post offices. And I'm not worried about Istanbul. I've read enough to know what of them will be open and on regular schedules and what will be closed. I'm more concerned about what I might experience once I get away from Istanbul.
Our plans include travel in the Black Sea area and then south to the Mediterranean Coast during the first two weeks of November. Kurban Bayrami is right in the middle of that time. I'm both excited about that and hesitant.
My only experience with major holiday travel is in the US. Here I'm used to finding office buildings closed (both governement and non-government buildings) and hotel open, But it isn't so uniform for other establishments. Finding an open restaurant is still a snap in the large cities, but once one leaves the cities and get into the rural parts of the country, most of them close up to be with family. The same is true of gas stations which will be openned or closed depending on whether in a high traffic area or not. And retail shops and minor attractions will most generally be closed for one day, but not the entire holdiay period.
So, should I expect to find similar unevenness as I travel across Turkey?
My expectation is that outside of cities like Bartin or Mersin to find little more than the hotels open on Sunday, November 6. But that the rest of the time, unless "mom and pop" simply closed their shop to go visit family, that I shouldn't have problems with anything else being closed the rest of the time other than the banks and post offices. So activities like sightseeing shouldn't be curtailed and necessities gasoline and food should be readily available even in the small towns except for that one Sunday.
Is that a fair assumption?
