For the past few years I've been running all the games. We have a dedicated spare room for games and crafts, and that is where all games I run occur.
Except I will start a new campaign at the game shop, or will meet new players there a time or two before inviting them home.
Since as "host" I feel my duties are fairly minimal (I provide water, ice, glasses and dishware, and ONE snack) that's never bothered me. Cleaning, sweeping, vaccuuming, etc... ahead of time is the worst chore!
