Hi,
On Wednesday I am having a spring break slumber party for
30 girls. My advice is to make sure you over plan. This is our third year planning this. We all meet at our local church in our Pj's. We play games, eat pizza, watch movies, sing karaoke,several crafts, there is rooms upstairs for those kids who need to sleep otherwise there is no bed time. My Daughters never go to sleep at this event. Basicly the girls run the evening. I always have 10 movies, lots of music all kinds, pizza for dinner and doughnuts for breakfast. We also have parents cell numbers available for those who can't behave. With a little planning we always have a great time. Just relax and have fun being a kid too.
If you are having fun your kids will, too.
Good luck!
