actors to the stage!

So I got invited to a mayoral forum! very excited to meet the other actors. I heard we have to bring our own wardrobe. Does anyone know if they have Hair & Makeup? I think the green room should be pretty nice because a lot of people wear ties and high heels. should be catered! maybe i can score a few snacks for later in case i get hungry. I hear sometimes people have an entourage like with their talent agents and managers and they bring their own props like spouse and children and notepads.  It should be fun. Are you supposed to thank the people who paid for your acting lessons? or just hook it upon the sidetip later? Gonna be so much fun! so much to learn from the pros!
