How is staying in a poncho shelter? I was thinking it would be neat to just carry a poncho and have my friend carry one too while backpacking then at night we can snap them together into a two man tent.

However one friend is trying to say I really should just get a hammock or carry a small 1 man tent instead, and that sleeping down in the grass really isn't worth it, because poncho shelters aren't sealed up so bugs and snakes can get in more easily.
