From my understanding the Worlds of Fun costume department aka "The Sparkle Factory" produces (or produced if that's no longer the arrangement) the costumes for the major seasonal events like Grand Carnivale and WinterFest at the legacy Cedar Fair parks. The individual parks likely take care of their own park-level productions, particularly at larger parks like Kings Island and Cedar Point.  

Tonight's visit to Winterfest was short and sweet! We only popped into the park for dinner, but still got to experience some of the magic of Winterfest during our time there. I used my Six Flags app in the park for the first time since the big v5.0.0 update and it worked every time I used it. We got to see about the first minute of Yuletide Follies on our way over to the Tannenbaumhaus for Swingin' Into Christmas. The line for LaRosa's felt a little long, but not enough to warrant opening the second line. We saw the show twice and I noticed that two of the performers were wearing the same costume. That's odd because normally all of the performers are wearing outfits that go together, but nobody normally has the same exact outfit. It's just something I noticed was different and led me to believe that someone else might've called in sick with this being a quick change. (Side note: I think I heard that the Cedar Fair costume department is based out of Worlds of Fun/Kansas City in general. Is that true?) I really enjoyed Swingin' Into Christmas and thought it was very energetic! The live band really helped and might be what was missing from Ghouls Gone Wild that made it feel so bland for me. 

Kings Island has put out its first round of America 250 merchandise in preparation for the national Quarter Millennium celebration coming in 2026. The new merchandise comes complete with the official logo (as seen in other park chains' celebrations) and a new park name/skyline design. Other patriotic apparel is available from previous releases. There are currently: a new America 250 t-shirt (big design on the front, logo on left sleeve) a new America 250 hoodie (big design on the back, logo on the breast) a new America 250 cross body bag (logo on front pocket, no KI logo) a new America 250 baseball cap (logo on front, no KI logo) an older patriotic Kings Island t-shirt (KI logo on the front, no America 250 logo) an older patriotic Kings Island baseball cap (KI logo on the front, no America 250 logo) I think the flag might be the only piece of AI art on the new merchandise (given it has 11 stripes at most and does not follow regular physical conventions between the obverse/reverse sides where visible) but overall looks very nice.

You buy it, I'll wear it    

Sadly I don't think we'll be able to make it for WinterFest... due to our busy holiday schedule but next year for sure!
