Birthday Pool Party...but what if it rains....

[Anonymous]

We are having DS's party at our neighborhood pool. We'll have 7 boys and 3 girls, ages range from 5-8. Kids can be super happy being in water for many hours, so we are excited. But if it rains, they are all coming to our house. We don't have basement, but have a large bedroom that we converted to a game room (board game, video game, etc). But I'm worried that we don't have enough stuff (toys, games, ideas) to keep 10 kids busy/happy for 2 hours...Do you have any ideas about how to entertain 10 kids at home when it's raining? Also, our house isn't so big and we dont' want parents to stay at the party...Should I notify them before the party that we prefer them dropping off the kids and come back to pick them up when the party is over? Or is it something that parents would know?
