Question about spaces for outdoor/camping projection

I'm trying to figure out a camping projection system using a cheap projector and a portable power station. To make this work, I know I need some reliable way to darken the space I'm using. I'm wondering if anyone has tried using one of these 10ftx10ft canopy tents as a makeshift/ portable theater. Basically, I plan on just getting 3 walls and screen to hang up on the inside. Please let me know if you've tried this/ like this/ have any other creative solutions!
