The Plaza San Antonio Hotel & Spa will open Thursday, bringing 253 guest rooms, a restaurant, a bar, a resort-style pool and a day spa to the revamped space that formerly housed downtown’s Marriott Plaza hotel, according to officials with the luxury property. The new addition to San Antonio’s hotel scene sits at the corner of South Alamo Street and East Cesar Chavez Boulevard. Repurposed 19th century buildings house the hotel’s day spa along with full-service restaurant Corinne and the Anaqua Garden Bar.
