I walked around the park (exterior) yesterday, doing a 5K Walk.
There were workers on site, And things are being done, such as the shade covering over the Charles Schulz Queue bridge/ramp.
Others have said that work is continuing.
That said, it might be ready to go at re-opening, or they might wait a bit to allow for testing. I think it depends on how much time "associates" get to prepare the park for opening, as they get to be the Guinea Pigs for the rids (DOSH rules only allow employees to ride prior to the ride's permit to operate).
Cedar Fair cut about half of its capital improvement projects, but left funds to complete projects that have been started.
But the rumor Knott's expansion took a hit.
