The timing of your hotel payment depends largely on how you booked the room and the specific policy of the establishment. If you booked a "Prepaid" or "Non-refundable" rate through a third-party site or the hotel directly, you have already paid for the room before arrival. However, for "Flexible" rates, you typically provide a credit card at check-in for a "hold" or authorization, and the final payment is processed when you leave. Even if the room is prepaid, you must still visit the front desk (or check out via an app) to settle "incidental" charges such as room service, minibar items, or parking fees incurred during your stay. Most modern hotels will slide a copy of your folio under the door or email it to you on your final morning so you can review the charges. If everything looks correct and you have no new charges, many hotels allow for "Express Checkout" where you simply leave your keys in the room or a drop-box, and they will charge the card on file automatically after you depart.
