Tarp suggestions. Please help. Family hang

[SADLK]

I am trying to decide on two tarps to purchase. We have a family of four that plans to do a lot of hanging this spring, summer and fall. Our children are 8 and 10, we want to attempt hanging two under each tarp. I don't think the children will do well on their own just yet so it will be one adult and one child (each with their own hammock). I'm interested in the Warbonnet Mamajamba with doors. Will these tarps be large enough for us? If not is there something that you would recommend? I don't plan to make a third tarp purchase for solo camping so the Weight of the Mamajamba is about as high as I want to go for now. Also, does anyone else hang double? If so do you have any advise for us on that topic?

Thanks
