I know this is part of their Summerfest, and available at RPR and PBH. From their site, not sure if it is permanent:

NEW YORK (June 11, 2008) - This summer, Loews Hotels introduces Summerfest, a brand-wide promotion that revs up summer fun with special stay credits of up to $100 (good toward dining, spa and even mini-bar raids, depending on the property) as well as special new activities that highlight each destination's uniquely local experiences. From dive in movies poolside to afternoon lemonade in the lobby, poolside pampering, resort sunset ceremonies and value-priced family-style menus showcasing regional cuisine, the Summerfest promotion makes summer travel more memorable and affordable than ever. Offered June 1 - Sept 30, Summerfest is available at all 18 Loews hotels and resorts in the U.S. and Canada.
This is also on their site:
Stay Credits of up to $100 from Coast to Coast
Loews Hotels and resorts offer credits ranging from $50 to $100 on stays of between two and four nights; amount and minimum stay vary by property. Depending on the property, the stay credit can be used toward dining, room service, spa charges and mini-bar. For example, at Loews Coronado Bay, guests who stay four nights receive a $100 stay credit good toward dining in the Market Café, Mistral and RRR's Market, as well as soothing treatments in the Sea Spa.
Guess I'll have to call and find out after the 15th of July and see what is going on.
