When we took the ferry from Trabzon to Sochi a couple of years ago the computers were down on the Turkish side. It took us 8 hours to get processed and on board. Plus the ferry was 8 hours late leaving. No rooms left, so we sort of slept on deck.
Getting into Sochi was only a couple of hours.
Both Trabzon and Sochi were great cities.
