thanks for posting. personally, i'll 'believe' "benefit" after first hand reports here
may be like LHW - expensive hotels available, booked few times, then excluded
(in other words, might be great for early users who book expensive early on)

MASTERCARD BENEFITS FOR THE CITI PRESTIGE® CARD (US)
INTERNATIONAL COMPLIMENTARY NIGHT HOTELS AND RESORTS PROGRAM TERMS AND CONDITIONS
You will enjoy a complimentary fourth night with no black-out dates, when you book four consecutive nights at any hotel booked by a personal travel advisor designated by MasterCard (the "designated travel advisor" is Carlson Wagonlit Travel). Bookings made through other methods such as, travel agents, websites or directly with a hotel will not qualify.
To receive your complimentary night (via a statement credit) you must:
Make a reservation for a minimum, consecutive four-night stay by contacting the Citi Prestige Concierge, to book directly with a designated travel advisor
Fully pay for your stay with a Citi Prestige Card
Receive one complimentary night (room rate for the fourth night and applicable taxes only) for any consecutive four-night hotel stay booked directly with a MasterCard designated travel advisor. Hotel imposed fees and incidental guest charges are the Cardmember's responsibility. The value of the complimentary night will be the actual rate, as provided by the designated travel advisor, on that fourth night of the reservation, even if the rate is different from the rate on other nights. Cardmember will be charged the total cost of the stay at checkout and will receive a credit to the credit card statement for the cost of the fourth night (and the applicable taxes). If the cardmember books a special "pre-paid" rate this may require upfront payment in full, at time of booking. Payment in full is defined as pre-payment for the total of all four consecutive nights. Only one complimentary night is eligible per each stay. A stay is consecutive nights booked and stayed on one reservation and does not include back-to back stays. Back-to back stays are stays at the same hotel booked on two reservations (as an example, you book four nights at a hotel on one reservation for Monday, Tuesday, Wednesday and Thursday and book another four nights on another reservation for Friday, Saturday, Sunday and Monday. In this situation, you would only be eligible for one complimentary night for the 8 night stay). Rates provided will be equal to or lower than the lowest publicly-available fare at the hotel's official website. The benefit can only be used by the primary account cardholder.
Statement Credit for Hotel Program
Fulfillment
All statement credits will be reflected on the Citi Prestige card statement as being a result of the Program and will appear within two billing periods following the month in which travel was completed; or in the case of promotional "pre-paid" that are paid in full as described above, rates the credit will be reflected within two billing periods following the date of payment in full of the "pre-paid" rate. Foreign exchange conversion rates may fluctuate resulting in slight differences in amount credited.
