Marriott International’s J. Willard and Alice S. Marriott Foundation has pledged to give UNLV’s hotel college $2.5 million to help build a new on-campus home. Construction for Hospitality Hall – a 93,000-square-foot facility housing classroom, laboratory and meeting space in the heart of UNLV’s Maryland Parkway campus – is scheduled to begin next March as the William F. Harrah College of Hotel Administration continues raising donations to pay for the $59 million project.
