Summer Trick

My good friend Angie gave me a GREAT idea a couple months ago when we were chatting about summer.
We were discussing the video game battle.
We have a wii and even though 70% of the games they play are active there are some that are just plain old video games.
I was trying to figure out how to handle it this summer so they don't want to play it all day long.
I didn't want the on going nagging and I didn't really want to monitor amounts of time EVERY day.
So here's the summer plan and on week one it's been going good.

We have a wii day each week.
We picked Mondays.
They know they can play on Mondays.
Doesn't mean they can play all day but for the most part they can play away.
If wii day Monday goes good . . . no fighting over it, arguing which game to play etc. then they can earn one extra wii day that week . . . we picked Thursday just to space it out.

We also took a 7 day break from all things wii leading up to summer just to take a break.
Everything is sweeter when you've been away from it for awhile.
We'll make exceptions if we are having family game time or something.

Do you have any summer tricks or things you set in place to make summer run smooth??
