Air mattresses can cure the occasional sleeping arrangements. Between the couch, wide open floor space with the full wall slide, and the 2nd bathroom, kids and grandkids are able to join us sometimes.
Ultimately they are mostly designed for 2 at the higher end. I chuckle everytime I hear the 6 for drinks, 4 for dinner, 2 for sleep. In fact that was the company slogan for the last 5er we had, trying to attract the babyboomers. In reality, that works for Florida retirement mobile home parks where everyone brings their own golf cart and leaves by sunset. Otherwise, I could never figure out how you selected who you get to send home with no dinner after drinks. I guess all your friends, and maybe even your spouse, get ranked daily so they know where they stand :).
