I think you're doing well! I suspect that, as others have said, the 'parents orientation' offered is about tryng to limit the helicopter parents and let them feel that they have some information.
When I was at university, my parents drive me there at the start of the first term, and wrote me letters while I was there, but other than that it was down to me. I used generally to make my own arrangem,ents for getting to and from university at the end of term and would let them know when I wanted to come so they could meet me from the station - as far as I can recall, they drove up at the start of the first term, the end of the first term, and at the end of the first year (when I moved from a hall of residence into a rented house) and at the end of the final year (moving out of the house) I can't imagine them contacting the University directly!
Even in my post-grad year when I was living back at home to save money, they allowed me to live rent free and use their second car to commute to university daily,but the assumption was that I was responsible for managing my time - they provided sympathy when I was grumbling, but didn't try to run things for me.
I can't remeber whether they drove me to any of the open days while I was applying - I don't think so, although I know they did drive my sister as the colleges she was looking at weren't easily accessible by public transport.
While I was a student, I did come across other students who were very helpless as they'd never had any independence and had never learned to do anything for themselves - I felt at the time, and still feel now, that their parents had not done them any favours at all. One student's mother used to drive up every weekend with a cold box full of single portion frozen home-made meals so all her daughter had to do was to re-heat them. She'd drive back with the week's worth of laundry. Goodness only knows when (or if, or how) the girl ever learned to do anything for herself. The first day we were there the same girl asked me how to make a cup of tea - she had literally never done it. She was 18.
