Yes, your credit card is required to guarantee your room. When you reserve your room with a credit card, the room is held for you regardless of your arrival time. This means the hotel is required to
hold your room for you until 7 a.m. on the day following your date of arrival. Your credit card information is protected according to requirements defined in the Payment Card Industry Data Security Standard.

Your credit card is not charged for your stay prior to your arrival unless the hotel has a prepayment or deposit requirement. If there are any prepayment and deposit requirements for the hotel you’re booking, a warning will appear during the confirmation process.
