We had 9 total "customers" -- 2, 4, and 3 at a time, between maybe 6:45 and 7:30. Maybe they get tired of Reese's Cups every year? It's fine with me, as my wife and I will handle the leftovers.
Also, a coworker of mine had about 50 visitors on her cul-de-sac, in a different city, county, and state. And another one in that county had 2, only because he was home at the time for the first time in maybe 4 years on Halloween.
