its going to be really hot so we planned the first day to be outdoor games and second day indoor games, and 2 sessions of free time where kids can do whatever they want.(hs students) activities such as swimming and football should be in freetime since not all will participate but funstuff and easy games like putting a spin on scavenger hunts and paper balloon catch..

another suggestion is making skits. theyre really fun and set a prize so that people are motivated to make good skits that follow the theme and help them.

thats all

edit:

i forgot to remind u. try to think of activities that everyone will enojy and take part in. =]
