HP AfterProm 2026 @ Six Flags Great America

HP AfterProm is an event immediately following HPHS Senior Prom that includes hanging out with friends, eating late night snacks, changing into comfy clothes, and making memories to last a lifetime.

Making the fun of Prom last a little longer for HPHS Seniors and their Prom dates—but also Seniors who didn't feel prom was their vibe, but still want to meet up with friends for late-night fun.

 Students will be bused directly from HPHS H Entrance to Six Flags Great America to keep the party going from 11:30 pm until 3:00 am with:

• Roller Coasters & Rides (no lines)
• DJ Dance Parties
• Chill Lounge with movies & snacks
• Game Show Entertainment 
• Raffle Prizes

ALL HPHS seniors and their dates, as well as HPHS seniors not attending prom may attend.

Because as parents, keeping our students safe on Prom night is our number one priority. 

• Auto accidents are a leading cause of teen deaths. One in three traffic fatalities in the state of Illinois is alcohol-related. (NHTSA)
• Roughly 29% of high school students drink alcohol, and 17% will ride with a driver who has been drinking. (CDC, 2019)
• Nine percent of youth in grades 9 to 12 use marijuana daily or nearly every day, an increase of 80% since 2008 (American Academy of Pediatrics, 2020).
• Prom night in Boulder, Colorado four years ago (2022) led to a fatal crash, and 9 indictments. 

It's fun, safe, and memory filled night to remember with HP AfterProm, substance-free, late night celebration for the entire HPHS Class of 2026.
