I enjoy going to parents' weekend - it's a great check-in time with your kid. They haven't seen you in a few months, they are happy to see you, they actually want to get a nice dinner together, and maybe share a little bit of their campus and experiences with you. I rarely participate in any of the school-planned activities - I'd rather do stuff on my kid. I have found that the school typically slows down the level of homework around parents' weekend, so my kid usually has some time he can actually spend with me, versus other random weekends. Since my son doesn't have a car - he loves the fact that I rent a car and we can go shopping, explore the area beyond his school, just get away from the campus. For me, the time together has been well worth the expense.
