It’s been a few years, but when my daughter attended scholarship weekend, IIT provided a shuttle to and from the airport and there were plenty of scheduled activities for the group of visiting students. It was well-organized. Meals were provided, there was a city tour offered as well as campus tours and lots of information sessions. She stayed on campus, and I stayed with a relative in the suburbs. The admissions rep was great about answering questions and helping us schedule everything. I called and spoke to her admissions rep a couple of times while I was figuring out logistics and buying plane tickets. Thursday to Sunday sounds like a lot longer than we were there. I remember scholarship weekend being just one overnight. We arrived late the night before and stayed in a hotel near downtown Chicago and may have stayed with relatives for a day or two afterwards but I think IIT only provided one night housing on campus for the student. Again, it was a few years ago.
I recall the students had a group dinner at one of the pizza restaurants in Chicago. My daughter somehow ended up with a glass of ice water spilled in her lap. Stressful, but she was awarded a Camras scholarship and had a great four years at IIT. Good luck to your son.
