This is the official word from Disney. It does not appear that they are refunding the PH portion of stand-alone tickets (non-package tickets). The option is use the PH option at a later date when PH is available (in other words, if you use the tickets prior to PH being re-introduced, you're out of luck and paying for an option you can't use) or ask
UT for a refund of the entire ticket. You may need to reach out to UT to find out what their policy will be on this.
"At this time, Guests will only be able to visit one park per day. If you have a ticket that includes the Park Hopper Option or Park Hopper Plus Option, we have several options available to you:
- Ticket Extension: You may use your current date-based ticket by September 26, 2021 with the existing add-on options, should the options return by that date.
- Ticket Modification: Resort Packages with tickets may be modified or cancelled. To discuss your options, please call the Disney Reservation Center at (407) W-DISNEY or (407) 934-7639 beginning June 22, or contact your travel professional.
- Ticket Cancellation: If you do not want to use your ticket, you also have the option of cancelling your ticket or package. To discuss your options, please call the Disney Reservation Center at (407) 566-4985 beginning June 22, or contact your travel professional."
