Hohoho, remember that instant noodles are most probably not allowed. Because the trainers are the ones that will be selling them. My camp enforced that.
There will be koperasi, but inflation rate is freakin' high.
You can buy snacks from koperasi or ask your parents to bring 'em for you.

the classes are basically self-reflection classes. plus, you get to play kiddy games in the classes. (oh and some brainwashing session)
on Saturdays there will be some light activities like ceramah all that..if you are lucky you get the day off
Sunday just sit and clean your room.( best time to catch up on sleep). Sunday is also family visitation day.

They don't let you jalan2 makan angin while in camp. but they do have buses for kids to go to church/temple/masjid etc.
and you'll get to go outside the camp to visit places like Rehab centres and such.
