Gov. Gavin Newsom's team visited Disney World weeks before issuing guidelines that have kept California theme parks closed.
The bill would allow theme parks in reopen in the "Moderate" tier of the state's COVID-19 reopening plan, rather than the "Minimal" tier.
Counties with major parks have seen dramatic increases in COVID-19 hospitalizations since early November.
Mayors of Los Angeles and San Diego were among those supporting a Tier 3 reopening for California's theme parks.
Theme park presidents used words like "arbitrary" and "unachievable" to describe California's guidelines that would allow parks to reopen amid the COVID-19 pandemic.
