I agree, the Six Flags name is much more recognizable with the masses. While it carries negatives it does carry with it some good connotations including, thrilling rides, a whole bunch of "firsts" in the industry, and is so popular that one saying, "I'm going to Six Flags" is almost synonymous with saying, "I'm going to my local amusement park." That's some pretty strong brand recognition!
If I were Six Flags, I'd be starting to think about taking the strategy of "underpromote overdeliver". Let's face it, their recent promotions over hype and underdeliver. I'm especially thinking of the MVP sale teasers and many of the new for 2026 rides now being delayed. Basically by underpromoting SF will set lower expectations and then exceed those expectations at the park by creating a positive experience for customers in multiple areas. This approach can build customer trust and loyalty back fast. This will also save some wiggle room for unforeseen issues such as delays or a necessary budget cut. But the key to this is that the company actually has to deliver quality. If they still deliver a cheap product, people will see it. Even if they market themselves as cheaper than cheap and change nothing, the quality or the lack there of will show.
I'm still hoping the best for SF, but I too see a "revitalization" going either way. It's still too soon to say especially with many moving parts such as core vs. non-core parks, company strategy, investments, board members still finding their fitting or being let go at corporate etc.
