It depends on where they want to go, what they want to do and how old they are. I will get clarification on our policy regarding non-gaming adults, but as of now, anyone over 13 attending the convention (including the vendor hall) must purchase a badge.
Kids 8 and under can enjoy free admission to the convention if they are accompanied by a badge owning adult. However, kids 8 and under are still required to buy individual game tickets if they wish to participate in games.
Kids 12 and under who are merely accompanying a badge owning adult may be present in the convention. However, if these children between the ages of 8 and 12 wish to participate in any convention activities they must register and pay for a badge and must buy individual game tickets to participate in games.
Kids 13 and over are required to have their own badge in order to attend the convention.https://www.gameholecon.com/attendancePolicies
