Our summer vacation cottage in Harbor Springs, right on (gorgeous!) Lake Michigan, used to house all the 8-10 cousins in one large "bunk house" bedroom, and the adults slept in the living room and two bedrooms. When we were on the beach or caravaning into town for a meal or ice cream, we looked like those clowns, too.
But, you know, that was the fun part of summer -- everyone all together, on top of each other, all eating on the beach together, older kids watching out for younger kids, always something to do and someone to do it with.
Great memories!
