L.S.
When my nephew turned 7 he had a camping party with about 10 kids. They didn't actually sleep outside, it was just the theme of the party. My sister had activities planned for the duration of the party so there wasn't much down time for kids to get into trouble. When the kids arrived, they picked up a scavenger hunt sheet and an empty goody bag. They had to use the clues to find their own goody bag items-- play compass, plastic canteen, candy etc. Then the kids did an obstacle course. (Post an adult at each station.) BIL had a canoe. Kids would run to the canoe climb in and then toss a blow up ring around a target. Then they had to use a sling shot and a peanut (in shell) to hit a paper target that was hung up. Next, they had to pack camping type items into a backpack and zip it up. Lastly, they had to fill a canteen with water and then run and pour it in a bucket. The kids were divided into two teams. They ran the course officially twice and luckily each team won once. But after that, the kids kept running it over and over and over. They loved this part of the party. After the obstacle course, they roasted hotdogs. (They had lots of adult supervision.) After eating dinner, serving cake and ice cream, and then opening presents it was starting to get dark. My BIL had put a white sheet on the fence and set up a movie projector using his computer. The kids wound down and watched the movie before going home. My sister heard the kids say more than once that it was the best party they had ever been to! I can't wait to do this party for my son in a few years! I know you didn't ask for a theme, but I just wanted to share. This party had aspects that appealed to all the kids, whether laid back or active. I think my sister's planning was what made the party go so smoothly. Happy Birthday! Have fun!
