Car Seat Pet Crate with Divider

how do you get the cats from the car to the hotel room if you can't lift it with cats inside?

Is there a video showing how to refold to put in carrier? The images aren't helping. I don't want to break it before I use it.

Would this fit a litter box plus some comfy space for the cat?

We've misplaced the fold down instructions. Is it a 180 twist for this lg double one too (it's zipped in the middle)?
