I went last Halloween too & thoguht it was great. The lines were not that bad, and I was under the impression that the 31st was the busiest night. I'd do it again - probably will this coming October. We did not get a lot of candy though. We'd get like one piece from each CM, while they would give a handful to a kid. :D
