Sorry for reviving an old thread, but this is something that I was just looking into.

I ended up making loops with double fishermans knots on each end with a Dutchwear double hammock whoopie hook. Then, spread the two side-by-side hammocks apart with two spreader bars (females with two tips) from DutchWare, also. They usually only go with us car camping, so bringing the poles is not an issue. If the day comes we want to do this backpacking, I'd heard of doing something similar with hiking poles. I like the idea of bunk beds, but I wanted my kids to be able to get in and out by themselves and thought they would like to be next to each other. This also means they are free to annoy each other.

Now, I just need to figure out how to get them well-sheltered with a rain fly...
