I have the passports of countries A and B neither of which require a visa to Turkey (to avoid doubt, none of them is Turkish).
I am planning to book a flight in passport A, present passport B at the immigration and use passport A when checking into a hotel.
What is the likelyhood that the hotel staff will check/question as to why there is no entry stamp in the passport I present to them? Would there be any issues with that?
I understand that it is normally not the hotel's business to worry about that but, in some countries, hotels are legally required to pay attention to foreigners and report to authorities if they suspect something might be wrong with their visas / border entry / allowed stay etc.
