They've been hitting self-imposed capacity, yes. For all we know, there may be operation changes about to occur in some way and they may be about to up that capacity. I wouldn't be surprised if we see F&F reopen for a few weeks to take the heat off of some of the other attractions, and also just open up more capacity for the park.
Remember, Universal could fill up to 100% capacity if they wanted per current Florida law, as COVID restrictions are gone.
