By Alison Fox – As Disney World prepares to open next month, the Happiest Place on Earth is introducing a reservation-based system aimed at reducing crowds and making it easier to enforce social distancing.

In addition to other measures to mitigate the spread of the virus, the parks will utilize its new Disney Park Pass System, which requires guests to make a reservation in advance for each park.

To make a reservation, visitors need to link their admission to their accounts and select the date they want to visit each park, according to Disney.

Guests who have a valid park admission ticket who are staying in a Disney Resort — many of which are slated to open this month — will be able to make their reservations starting on June 22.

Travelers who want to book a new vacation or purchase new theme park tickets will be able to do so starting June 28, but for arrivals starting in 2021, according to Disney.
