I could just feature myself in this thing and I finally get comfy and the water sounds so nice and everything and all of the sudden, I gotta pee. Now for a guy, no biggie, well maybe. You can't stand up in it. It's going to be inconvenient.
The other thought was not paying attention to where this thing is going while sleeping in it and finding out you are stuck to a barge 100 miles from camp in the morning. That uber ride is gonna be expensive.
And John has it right for my neck of the woods anyway. Gators would look at this as people in a Chinese take out carton.
