Hilton Worldwide signed an agreement in Spain last week to convert the Barcelona-area La Mola Hotel & Conference Center to a DoubleTree. The renovated DoubleTree by Hilton Hotel & Conference Center La Mola will open at the beginning of 2013 in the Sant Llorenc del Munt Nature Reserve, just north of Barcelona. The 186-room property has nearly 48,500 square feet of meeting space, including 26 meeting rooms, two ballrooms, two 54-seat auditoriums and a videoconferencing room. An adjoining 17th-century manor house may be used for events as well. The property, DoubleTree's second in Spain, also offers a spa and an on-site restaurant, and is adjacent to a 45-hole, Greg Norman-designed golf course.
