i’m referring to the upcoming red velvet concert(s). (i asked a day ago: can someone 13+ go without an adult? is video/photo-taking during the event allowed?

Yes, we will allow entry to a 13 year old. The photo policy is up to the discretion of Red Velvet and their management team.

Im not sure about that one but i would think not i think a adult has to be with minor

Can't help you sorry I only went there once for a Salvation Army event. Try calling the box office for information.
