The Citi Prestige 4th night free benefit gives cardholders a free night when booking a hotel room for at least 4 consecutive nights through thankyou.com or over the phone at (800) 842-6596. You must pre-pay your reservation to qualify for the benefit. The cost of the 4th night is subtracted from the total amount due when you make your reservation, before you enter your payment information at thankyou.com.

Below, you can check out other requirements and tips for using this benefit.

Requirements for the Citi Prestige 4th Night Free Benefit

• The booking must be made through thankyou.com or over the phone at (800) 842-6596.
• The primary cardmember must make the reservations, but bookings can be made in the primary cardmember's or authorized user's name.
• There's a limit of two free nights per year. This limit is cumulative for all users on the card.
• The stay must be for at least four consecutive nights.
• The 4th night benefit is intended for personal use. You cannot use this benefit for business travel.
• The benefit doesn't apply to any packaged or bundled rates. You'll have to book the hotel separately from other travel accommodations to take advantage of the reward.
• If you're booking multiple rooms for your stay, the 4th night free offer only applies to one room.
• Only 1 free night is available per stay, even if you book back-to-back reservations at the same hotel. For example, booking 8 consecutive nights will not earn 2 free nights.
• According to Citi, rooms in “yachts, riverboats, cruises, campgrounds, castles, safaris, villas, and apartments,” do not qualify for the Citi Prestige 4th night free benefit.

When you book a hotel reservation, either through thankyou.com or over the phone, you can use your Citi ThankYou rewards points alone or in combination with your Citi Prestige card. In addition, for every $1 you spend on hotel reservations with Citi Prestige, you'll earn 3 ThankYou points.

How to Book Your Free 4th Night Online with the Citi Prestige Card

1. Visit thankyou.com and log in to your account, using your credentials.
2. Select “Hotels” from the “Travel” dropdown menu. Then, select your destination, preferred hotel and desired dates.
3. Choose the number of points you want to redeem, or elect to pay for the entire stay with your Citi Prestige card.
4. Lastly, confirm your personal information and enter your billing details.

Keep in mind that the amount deducted for your free fourth night will be based on the average nightly rate during your stay, minus taxes and fees.

In addition, booking through thankyou.com provides no opportunity to enter your hotel loyalty membership details, and thankyou.com is technically a third-party booking service. As a result, 4th night free bookings do not yield points with some hotel loyalty programs or count toward their elite status.

You should try mentioning any loyalty program membership or elite status to the hotel when you arrive, though. They may choose to make your booking eligible for points, or at least provide membership benefits during your stay.
