Often the best value of the season: trivia nights, themed dinners, scary-movie bar screenings, and early crawls run cheaper, quieter, and more conversational than peak Saturday. Weeknights suit costumes you actually want people to look at, and bartenders have time to make the themed cocktails properly. Save the marquee spend for the big Saturday and fill October's calendar with weekday gems.
Older bars are the wildcard, basement venues, narrow doors, step-up entries, so call or message the venue about step-free entry and accessible restrooms before buying tickets, and ask where the accessible entrance actually is, since it's often around back. Crowded costume nights complicate navigation, so early arrival helps. Ticketed seated events, themed dinners, cabarets, are generally the more reliable choice.
The Saturday before Halloween is the main event: biggest parties, biggest crowds, and the night costumes are mandatory. Halloween night itself skews mellower with locals and die-hards, often with cheaper covers. Big years give you both weekends, so split them, marquee party on peak Saturday, favorite neighborhood bar on the night itself. Fridays split the difference on price and crowd.
