"Along with the new safety guidelines, there will also be one major difference for anyone hoping to ride the roller coasters, if they end up being a part of the reopening plan:
no screaming.
That may sound silly but California’s Attractions and Parks Association is
recommending that theme parks “mitigate the effects of shouting” in order to reduce the risk of spreading the coronavirus. It is also recommended that singing is discouraged as well, as it has also been linked to spreading COVID.
That being said, it looks like Disney California Adventure Park
might not be opening their rides at all — or will be operating the rides at a limited capacity, in accordance with California guidelines. So the silent rollercoasters may or may not be a dystopian reality." (source yahoo news)
Again, oh blessed state of California, WDW is doing okay with this.
