Have to Turn Lights Off for 2 Days on Seedlings, Will They be Ok?

Long story short my family is coming by and I can't have light pouring out of my grow box. I can't seal all the light in without restricting the air-flow and making it hot as hell in there . So... I can either turn the lights off for 2 days or have all my plants burn up. They are just 2 weeks old, so I would still consider them seedlings. Will they be OK or will this stress them or affect the grow?

Thanks in advance for any input!

you cant stash them in a window for 2 days or something?? and if that all you can do the thats all you can do... they will be yellow as fuck and maybe taller stems, but they will live.. blast them with the light 24/7 till then
