Direct buses from IST may have limited or unreliable evening departures. For more options, it's safer to travel from IST to Esenler Otogarı (Istanbul's main bus terminal) using Havatas buses (from platform 5, approximately every half-hour). Purchasing Arda Tur tickets from Esenler Otogarı is possible through Tutu.ru, allowing payment in rubles with Russian cards, but it might be more expensive. Arrival at IST: Passport control and baggage claim can take 40 minutes to over an hour, making a tight connection (e.g., 5 AM arrival for a 6 AM bus) risky, especially with checked luggage.
