Do I have to guarantee my reservation with my credit card?
Yes, your credit card information is very important for making a reservation in Polish hotels and necessary for receiving special rates. Polish hotels require either a pre-payment or credit card guarantee and acceptance of their individual cancellation policies.
If you did not have to guarantee your reservation, the hotel would risk turning away next customers and in result being left with an empty room and no payment. Credit card guarantee is a standard procedure in the majority of countries in the world.
