Visit

Yes. It's fine. But let your son ask most of the questions. The tour is for him. 

Agree with jbb.  I think it's fine to go, and I would go so far as to say it was expected.   Most coaches I think understand that there is a family component to this decision and I think coaches may want to observe some of those parent interactions with the kid.  Further, unless your kid is a 100% scholly guy (very, very rare) the chances are the family is going to be kicking in tuition dollars, so I think its fair to assume the family wants to see the place.  That said, I completely agree that the player should be the one doing most of the talking and asking most of the questions.

Yes, my wife went on one and I went on another where our schedules did not work. We both went on a few others. Typically your son will likely stay with someone on the team and have a different schedule than yours. You will likely get a formal tour of the school as a group and possibly a meeting with admissions, financial aid, etc. Justbaseball is correct on letting your son ask questions, but we actually made a list and practiced them with him so he felt more confident and had thought through what to ask. I did ask questions of the head coach when I felt it appropriate, but let my son take the lead. 

Yes go.make sure you have discussed what ? For son to ask before so he is prepared. At the end if he has forgotten to ask about a subject that u feel is very import it's ok to bring it up, just don't take over the experience. 

Thanks for all the input!  2015's first visit was him nodding and briefly answering their questions.  Was killing me because he's typically not shy.  We discussed in the car, and the second one was much better.  Thanks to baseball for giving my son this type of experience/learning moments 4-5 before his first real job interview!  

WB, you've obviously received good information and feedback from the other posts.  If you're interested in another resource, our son (a former DI baseball recruit, and current Division I athletic academic advisor) and I have written "Informed Athlete's Guide to Campus Visits" which includes the NCAA official and unofficial visit rules, as well as tips on questions to ask and things to look for during the visit.  The Guide can be found in the Store of our website here:  http://www.informedathlete.com/store

Been on a few visits and both my wife and I went along.  We plan on going on several more once the summer season ends in another 10 days or so. Our 2015 experienced his first in-home visit and that was a great experience for all of us.  I think they were at our house for three hours.  Wife even cooked them dinner.
