When leaving the Holiday Inn on Lytton Avenue, head down to Fifth Avenue. Turn left at the bottom of Lytton onto Fifth Avenue. Follow Fifth Avenue to South Craig Street (you will pass Mellon Institute and the Software Engineering Institute and see a Mellon Bank on the corner). Turn right onto Craig and follow it until you reach Forbes Avenue (the Museum of Art will be directly in front of you). Turn left at Forbes and continue until you cross the small bridge.
Continue up Forbes Avenue, past the Morewood Avenue (the first intersection you will encounter). Warner Hall will be on your right. This is the main entry to campus. Follow the sidewalks to the University Center, the large, cream-colored brick building with columns directly in front of you.
The Holiday Inn is just off this map on the right side as you continue on Fifth Ave.
