Though Walt Disney World and SeaWorld Orlando have announced that their parks are closed until further notice, several parks like Universal Orlando Resort and LEGOLAND Florida have said that they are hoping to reopen by mid-April. However, it looks like new regulations from the United States government have been put in place that have officially made it impossible for any theme parks to open before the beginning of May at the earliest.
Social distancing guidelines in the United States are now in effect until April 30th
The United States government has officially announced as of Sunday March 29, 2020 that it will extend the social distancing guidelines for another 30 days through at least April 30 2020, past the initial 15 day-long guidelines announced two weeks ago to control the spread of COVID-19. These guidelines specifically limit on the size of large gatherings and keeping vulnerable groups at home.
According to a speech made by President Trump, the expectation is that by June 1, 2020 businesses may be able to return to normal operations, which is in line with the reported internal projections by Disney, which has stopped all reservations for dining, hotels, and more from now until that date.
Right now there have been no statements from any theme park companies about these extended social distancing guidelines, but we'd expect some official word confirming these extended closures some time in the near future as the situation with the spread of COVID-19 continues to evolve.
