My son trick-or-treated "around the house". He'd knock on a bedroom door, then dh or I would open it, and ds would do the whole "trick-or-treat"/"thank you" routine. Its nice having an easy-to-please child!
We handed out glow bracelets this year thanks to the suggestion of valeriemates on a thread here prior to Halloween. They were a big hit! Thanks for the idea, Valerie!
