A new disclosure on Monday is informing lodgers at Holiday Inns, Marriott and Renaissance hotels that they may be victims of suspected point-of-sale device attacks.

White Lodging Services, a hotel management company, disclosed that sometime between March 20, 2013 and Dec. 16, 2013 suspects that point-of-sale systems at restaurants and lounges on 14 of its properties were compromised.

The company runs more than 169 hotels in 21 U.S. states.

“We deeply regret and apologize for any inconvenience caused by this incident and remain committed to protecting all information entrusted to us by our guests,” it said.

The U.S. Congress is planning on holding hearings tomorrow (Wednesday) with Target and Neiman Marcus along with the U.S. Secret Service about how data breaches can be prevented.

White Lodging listed the 14 affected facilities in the states of Illinois, Texas, Pennsylvania, Colorado, Texas, Indiana, Virginia, Kentucky, Florida and Colorado. It includes seven Marriott, two Holiday Inn and two Renaissance hotels, plus one Sheraton, one Westin and one Radisson hotel.
