Going to visit Michigan as a junior next month...questions

I am a junior (OOS) and I am going to visit Michigan next month - one of my parents graduated from there and we are going back for a football game with college friends. We set up an official tour while we are there. Since it is early in the process, I am not really “ready” to do anything more than just go on general tour and get a further feel for the school. I am sure that I will go visit again next fall when I will be more prepared with my essays, application etc.

Is it a mistake not to be more prepared now? Is there anything else I should do while there next month to show interest?

No, just have a good time.

Make note of the dates of your official tours and other activities that demonstrate interest. You’ll be asked for that information when you apply.
