Like other's have asked, how long will you have them. If it's just a few hours.... I wouldn't worry too much about it....They are old enough they should be out of the "I want my mommy/daddy" stage, so I know you have the projector.....And if you have even the shittiest of game consoles, that'll buy you some time. You seem to live in an area surrounded by woods, so if you are even the slightest bit outdoorsy, take em outside....That'll wear them out. This world has really taking the value out of kids going out doors....The come in smelly, but after they bathe and eat, it's a wrap.
