The hotel was acquired by the university in 1970, and the Addition (designed by J. Robert Hillier '59) was built connecting the Annex and the Main Inn.

From 1970 to 1983 the hotel was called the Princeton Inn College, which cultivated a unique campus culture; residents were called "Innmates" and T-shirts with the slogan "Die For the INN" (an intramural sports battle cry) still remain in circulation.

These include private bathrooms for many of the suites (for rooms in the former hotel portions, plus a few in the Addition), and a dining hall, library, theater, and café that can be reached without ever going outdoors.

Only first- and second-year students (with the exception of several upperclass Residential College Advisors) lived in Forbes.

Over dinner, about two to three times a semester, invited guests speak to Forbes residents about their travels, their work or research, their latest publication, or simply provoke with some unconventional ideas.

Friday afternoons at 4:00 p.m., the College Office staff invite students to join them for tea and pastries and some informal conversation on just about anything.

Members of the Forbes community are encouraged to join the FFS and participate in organizing screening schedules, to work as projectionists, and to share in the pleasure of watching and discussing a good movie in the company of friends.

The Forbes College Council (FCC) consists of twelve to fifteen representatives of the student body.
