South Loop's Congress Plaza Hotel to Host Chicago's Largest Halloween Costume Party

By Socialhood News · Il/Chicago/South Loop ·

South Loop's historic Congress Plaza Hotel is preparing to transform into one of the city's most thrilling Halloween destinations on October 31, 2025. The Haunted Halloween Ball, billed as Chicago's largest costume party, will convert the hotel's 20,000 square foot ballrooms into a spooky abandoned hotel experience for one night only.

The event combines elements of a luxury VIP nightclub with the chills of a haunted house, taking full advantage of the Congress Plaza Hotel's reputation as "one of the most haunted hotels in the world" according to USA Today. Located on Michigan Avenue adjacent to Grant Park, the venue will feature multiple premium bars, live DJs, and a $2,000 costume contest with cash and prizes. Early bird tickets are currently available starting at just $20, with VIP table packages also available.

South Loop residents looking to participate in this neighborhood spectacle can purchase tickets now, as prices will increase closer to the event date. For those wanting the complete experience, the hotel is offering special Halloween weekend room rates of

59 per night until October 25 or until the reserved block sells out. This 21+ event runs from 9:00 PM to 2:00 AM and promises to be one of South Loop's most memorable Halloween celebrations this year.
