Yes, you may use Hotwire's Add to Your Stay web site feature to book additional nights at a hotel where you already have a reservation. Provided there is availability, the additional nights will be booked as a new reservation. This means you'll have two consecutive bookings at this hotel along with separate confirmation emails, confirmation codes, and credit card charges. Your original reservation will remain unchanged.
You may add nights either before your original check-in date or after your original check-out date, but not both; additional nights will be booked for all rooms in your original reservation. Note that the maximum duration of your combined reservations may not exceed 30 nights and you may be required to change rooms during your stay. Hotwire's Low Price Guarantee does not apply to reservation extensions. For Hotwire Hot Rate and regular rate bookings, the cost of the additional night(s) may differ from your original reservation.
To add nights to your stay, go to My Account and view your Active trips. Find the hotel reservation for which you'd like to book additional nights. If an "add to your stay" link appears below the hotel name, simply click on it to complete a related booking. This feature is not available for all hotels. If this link does not appear, call the hotel to book additional nights directly.
