I’ve never seen/heard of a sukkah hop where kids bring candy bags– the entire point is to eat the candy in the sukkah!
We spent yom tov in a small but growing yishuv. The sukkah hop used to just literally go around to every sukkah, because there were about thirty families, but as more people moved in this was no longer possible. So the family we stayed with told us that last year, the sukkah hop was not scheduled to stop at their sukkah, but then their youngest child (about four or five) started crying uncontrollably when he found out, so the leaders of the sukkah hop decided to make an unnscheduled stop to placate him 🙂
