How much contact is too much contact for juniors? Are we allowed to pop in and visit quickly whilst touring? Or no personal contact at all?
I would at least email them first to say you’re coming to tour the campus and to see if they’re available, but meeting with them isn’t usually a big deal. It’s considered an unofficial visit but if you’re already going to be on campus it’s definitely worth seeing if you can meet up with them to save yourself an additional trip later on. Plus your parents will most likely be with you so they can ask the coach any questions they have too. I wouldn’t just go straight to their office with no prior warning though because that’s a little … weird, especially if you haven’t had much contact or interaction prior to that. I don’t think the NCAA has a definition of “too much contact”, at least from your end, but you should be able to use your common sense to determine how much is too much.
