If your house isn't big enough for all the people in your life, get the ginormous Marmot Limestone 8 Person 3 Season tent, sell the house, and invite all the in laws to live with you in spacious, durable, waterproof comfort. It doesn't have a bathroom or running water, but the Limestone has plenty of things your old house didn't, like a waterproof polyester fly with fully taped seams, breathable no see um mesh, and rugged polyester and nylon walls and floors that can stand up the abuse that's an inevitable part of living outside. It's also ridiculously easy to set up, needing only five DAC aluminum poles that pair with color coded clips and sleeves, and comes with two doors and vestibules for storage space, so you don't have to bring wet gear inside with youthink of them as your new dual mudrooms. If the youngsters get rowdy, or the grown ups need some alone time, you can set up the removable room divider and tell the kids to go to their room. They'll have plenty to do, since the interior pockets will probably be packed full of games, books, and snacks. There are other thoughtful touches, too, like reflective guy out points so you don't trip over the lines at night, and jingle free zippers so the breeze doesn't make a wind chimey racket. Maybe it doesn't have a dishwasher, but it's better than your old house in every other way. Kind of.
