I am having a sleepover for 6 girls.... ages 9 and 10 for my granddaughters 19th birthday party. I will be present but need someone to help handle activities with me. I plan on having a few inside and outside things for the girls as well as snacks and crafts. I plan on starting around 630 p.m. and would need someone until 12:30 p.m. or a little later if you can
