How old do I have to be to go to finals?

Ok guys I really need help, the finals are tomorrow and I don't know if i can go alone. I'm 16 years old and I have tickets for the NA LCS Summer Finals and I am really pumped for them. The thing is I don't know if I need someone to go with me because of my age. I couldn't find anything about age restrictions on any forum posts or posts by Riot. So please help me I need to know.
