Unfortunately - no.
Hotels require a credit card number to secure a reservation.
If the guest does not cancel the reservation within the cancellation notice period and does not arrive at the hotel, the hotel will charge the credit card for the first night's accommodation. Without a credit card the hotel risks being left with an empty room with no one to charge for it. Please refer to Cancellation Policy for more information. While the hotel has your credit card number, no immediate charge is made. Payment details are decided upon by the client upon arrival at the hotel.
