UT does refund tickets for both parks and special events. UT additionally refunds (95%) certain types of party tickets if you
choose not to go. I don't believe Disney refunds tickets if you choose not to attend.
One clarification, UT will refund 95% of event tickets that are mailed, not etickets. You have a 90 day refund window.
As noted above, UT will refund 95% if you choose not to attend the party. It's written on their special even ticket page under refunds. This is for mailed tickets. Etickets don't have the refund policy.
Just a note that we've used UT many times over the years for Disney parks, Uni tickets and MNSSHP tickets and never had an issue. We had our tickets for May when everything was cancelled and getting a refund from them was super simple. They are amazing people to work with and very accommodating. Another note we learned from this past experience.... you CAN link a ticket to
MDE and still be able to get a refund if needed. Again, this is for mailed tickets, not etix and if you're within your 90 day window.
