Heigh-Ho Kim,
I am a little bit confused by your question but want to try and help. You say you are arriving Sunday, October 24, 2021. And on your arrival day inquire about seeing the First Time In Forever: Frozen Sing-Along Celebration at Disney's Hollywood Studios and making a dining reservation, which you did not state where the reservation was. And then ask if it is possible to do both on Thursday? But you claim you don't have a park reservation? I am going to try and answer as best I can but, PLEASE,
feel free to reach out to me with more clarification.
In order to join Anna and Elsa and their storytellers in this amazing musical, at Disney Hollywood Studios, all Guests will need a valid Walt Disney World ticket and Disney Park Pass reservation. The show is performed multiple times throughout the day. To see showtimes for the specific day simply follow this link to the
First Time In Forever: Frozen Sing-Along Celebration page and select the date you are interested in to see current showtimes. Once you see the showtimes and depending on where and when your dining reservation is, hopefully, you can determine if you are able to do both.
But if you need more information, again, please ask I am happy to help.
Have a Practically Perfect Day,
Amy M.
