Check out Denice's website? She always has great ideas for keeping groups of boys entertained! :)
Karate Kid? for movie.
Don't know if you have seen Minute to Win It, but we have been creating our own little challenges and doing them with the girls. It has been so fun...sometimes I can't stop laughing.
Check out their site for ideas for challenges:
Hmmmm, Marie and Karol had some great ideas.
Everyone else has great ideas. How about doing an "indoor campout". You could still do hot dogs and they could all top their own hot dogs...hot dog bar, if you will. :) You can make smores in the microwave. Have popcorn. They still make Jiffy Pop to do on the stove. That's campout-ish. I think Goonies is a great movie. My kids love it. Other old movies...how about Gremlins or ET?
For a game you could play flashlight tag. Along with popcorn have trail mix as a snack.
I Googled campout party ideas and a lot came up so you could check that too.
