For my DD's Birthday she is having 9 of her friends from school for her first real sleepover experience. I am a little worried it will all end in tears. Id appreciate any tips for a smooth night - I'm not expecting much sleeping! - to complicate things a little I teach in the school they all attend! plus I'm a lone parent so I will be the only adult. She plans to make the party into a movie marathon - back to back movies with cinema themed snacks.
