My mom came with me when I went two years ago, and while all the students were out and about doing our own thing (running around campus looking for buildings, i can't even remember)... all the parents got a little talk about some info that they would need, as our parents. My mom really liked it and foudn it useful. She also made a friend, lol.
So yea... if its not too much work for your mom to take work off, def bring her
