Hi Legi,
The tour and lunch are given on the main campus, and if you opt to interview at a different campus, you have to use the shuttle service to get back & forth. My interview was at Morris Park, but there were several other interviewees with sessions at the other campuses, and they were concerned throughout the afternoon that they would be late for their interviews. I'd recommend an interview on the main campus, if that's at all possible. Just know that the day is not particularly well-structured, and I'd recommend that you arrive on time, but NOT extremely early...I inadvertently arrived far earlier than scheduled, and the admissions office was not even open.
Good luck...it's a wonderful school!
