Hi It looks like I will be taking a trip out there sometime in October. The exact time is to be determined, but it looks likely to be one or two weekends before Halloween. So, I was curious... I've never actually been to Vegas for Halloween, but I assume there's likely to be plenty of costumes. But how early do they start coming out? Halloween is on a Saturday this year, so I'm guessing it'll likely be just that Friday/Saturday night? Any input appreciated, thanks!
