During the covid shut down Disney announced they would wait to begin new park ticket sales and hotel reservations until guest with cancelled reservations and annual passholders had a chance to book once the parks reopened. Since the resorts have been open for a few weeks and the theme parks are set to reopen next week Disney announced that they are opening reservations and ticket sales back up to the general public beginning July 9th. Guest will still need a reservation to be admitted into the park so they suggest you check the calendar to make sure space is available before buying your ticket.
