Because not everybody can adjust their flights, nor their time-off from employer. Many people don’t take luxurious 7-day vacations at Disney, but instead do 1- or 2-day park visits.
This is only 9 weeks notice. A good portion of visitors have already reserved hotels, flights, car rentals for that day. Some have already made Advance Dining Reservations using the 60+10 rule.
Based on historical data, ticket-purchasers have a “legal reasonable expectation” of a traditional-full day for their purchase price. Disney needs to refund or otherwise provide partial compensation for changing the deliverable after selling it.
Disney Employees deserve a party and I’m all for that! YES!!! But not at a time that causes domino financial impacts to paying-customers — Unless Disney provides refunds or compensation for choosing to not deliver the reasonable expectation. This certainly could’ve been scheduled sooner than now. Was Disney uncertain until the last minute whether or not its employees deserved a party? Good grief this is the time to schedule a 2024 party, not Jan 2023 party.
