I find it interesting that Six Flags made a pretty big deal about this announcement, but left out many of the most popular legacy Cedar Fair parks. Many of the regional parks not mentioned here are hosting Holiday events this winter, so perhaps the chain is taking a wait and see approach to continuing the events at these parks in 2026 and don't want to announce next year's calendar until they're sure they want to commit to another year of Holiday in the Park/Winterfest. If you enjoy these events and live near a park that is running a holiday event, make sure you get to the park so these events don't completely disappear from the calendar.
It's probably also worth noting that Six Flags finally consolidated their parks into a single mobile app, so if your "home" park was a legacy Cedar Fair park, you will be directed to download the Six Flags app the next time you open the park app.
I assume that the timing of daily operation is dictated more by local school calendars than anything else. That affects both demand and staffing supply.
Interesting mix of opening dates this time. The staggered daily schedules especially for parks like SFNE and Darien Lake really make it feel like staffing and early-season demand are big factors. Also curious to see when Cedar Point and Canada’s Wonderland announce, since those usually help set the tone for the whole spring lineup. With some parks testing Holiday events this winter, it does seem like they’re waiting to see what sticks before locking in 2026 calendars.
SF over Georgia seems to have had a great deal of difficulty loading their schedule in recent years. Their 2025 operating calendar was not made known until around the beginning of February last year and even then, only the calendar through mid-August was populated. Operating dates for fall and Fright Fest were not known until August! While I am not normally one to complain, members and pass holders should be informed as to 'what we bought.' With most of the other parks in the chain and elsewhere having published their 2026 schedules, what is SFoG waiting for?
Was very disappointed this year with Six Flags over Georgia. Bought two season passes and planned to go twice:with my college age daughter: during summer and in December. Two visits would make sense to buy a season pass. Season pass was good till January 6, 2026. But in November, Six Flags over Georgia announced that they will close on November 30, no holidays at the park. This is really bad business. If I knew that, I would just buy one day tickets during summer visit. Basically got scamed by SFoG.

Kinda weird that SFNE and SFDL don't go daily until late June. Maybe a staffing thing.
