Robert asked:

Is travel from Istanbul to Iznik a problem during October 12, 13, and 14 (Friday, Sat, and Sunday) because of the end of Ramadan and the 3-day Sugar Festival?

On Saturday, October 13, I am trying to travel from Istanbul to Iznik (ferry via Yalova) and back all that same day. Will this be a problem? Any suggestions are appreciated. Thank you.
