I'm currently renovating my game room and looking to get a Great American 8 oz popcorn machine for my wife but have some questions and hoping that someone can help me.

Will an 8 oz machine be too much for a family of 5, of which only 2-3 love eating popcorn? I'll eat them if they're flavored like cheese or even better...covered with chocolate But it's mainly my wife and maybe 1 of my daughters currently living with us that eat popcorn. My oldest daughter recently moved to Chicago to start a new job but expects to be back visiting and she loves popcorn like my wife.

Is it possible to pop any amount like 2 oz instead of 4 or 8 oz in an 8 oz machine? I know that Great American says that you can pop 4 oz in the 8 oz machine but there's no mention of going even smaller. I'm concerned that 4 oz might be too much so I'd like the flexibility in popping smaller amounts.

How long can popcorn be stored in the machine before it gets too stale to eat?

Thanks much for your help!!
