I was in my late-20's and I took my parents with me the first time and mother with me the 2nd. It was nice to have someone there to calm my nerves
There are a lot of parents there, they will not be bored either. They will have different things going on during the interviews, also some of the parents will sit in the coffee shop area and talk to one another.
Like I said... I had no shame taking my parents
I was nice to have my mom there to keep me from having a nervous breakdown when the rental car got a flat tire during interview day!
