It's certainly possible that's how they view USF internally.
I could not disagree more with that view, though. Epcot kind of languished for years, in terms of attractions, because management allowed it to be propped up by special events, to such an extent that a massive, multi-billion dollar overhaul was eventually implemented (to lesser or greater effect)... and that park still isn't in the greatest of shape.
Letting eight weeks of HHN dictate that USF is just fine as-is*, and doesn't need serious work because HHN brings in the big bucks, is a terrible strategy for the long-term in my view. The park is open for 52 weeks a year; it should be a world-class experience for all 52.
* I'm classifying "as-is" as things that do not fundamentally shift or rebalance the park's attractions offerings.
Which is part of the reason some of us had been identifying an urgency to see USF course-correct for seven or eight years now, to get out in front of all the other investments (Epic, the U.K. park, Horror Unleashed, the Texas park) that are now taking up more of the company's bandwidth.
