We are disembarking in Istanbul after Mediterranean cruise with NCL and staying 2 extra night in Istanbul in hotel. Turkish embassy web site says that US passport holders can buy Visa in port in Istanbul at arriving with cruise ship, also I have email from Turkish Consulate with confirmation to buy visa in Istanbul port. For some reason agent and NCL reps suggest to buy visa in States. Is any one had a problem to buy Visa in Istanbul port at arriving. Different in price is huge, also have no desire to send out passports out before cruise if it's not absolutely must. Please reply anyone who has this experience. Thank you in advance.
