I'm not a fan of houseguests either; I like my routine, and I always stressed out over meals, house cleaning, what to do with them during the day, TV preferences, ETC!
Being a traveling nomad is perfect...I no longer have a place for guests. I know it disappoints our parents not to be able to visit us, but we visit them, and they always seem thrilled to have us visit. Works out well all around.
