DD will be 7 soon and I'm really struggling for ideas. Basic list of about 16 girls plus Dd, and DS may tag along too. Don't mind hiring a hall or doing it at home. we've had several entertainer or bouncy castle type things so want something different. Build a bear too expensive for that number and everyone hates swimming parties as they have to go in with their child!Do't want to exceed £7-8 a head really.
