I am an introvert, so my need for "down time" can be an issue whether being a houseguest or hosting one. And, as I get older I am less able to be comfortable crashing just anywhere. And, my last visitor informed me that I snore!
All that being said, I find my favorite part of extended visits with friends and family happens at the beginning and end of the day. Lazy mornings chatting over coffee, cozy evenings at home. Maybe because it feels less like a formal visit and more like we are just hanging out together like we used to. Luckily, most people I know have the space. I would not want a friend or family member to overextend their budget or sacrifice their daily comfort for my very occasional visits.
