Hi Anne,
Welcome to the Disney Parks Moms Panel! Kudos to you for getting a reservation at
T-REX™!
To link your dining reservations, you will need a confirmation number. I had a similar issue with an initial reservation I made at The Edison because I had booked through another service initially. Eventually, I changed my reservation and booked directly through the Walt Disney World Resort so that it would link in My Disney Experience.
If you are unable to make an
advanced dining reservation through the Walt Disney World Resort, I would make a note of the dining reservation in My Disney Experience. To make a note, I always login to My Disney Experience from my laptop or iPad. Then I click on My Itinerary. From that screen, you should see an option that says Add Plans. Once you add a note, you should be able to see that note in the
My Disney Experience Mobile App as well. I use the note feature to keep track of our special experiences. For our upcoming trip, one of our girls is doing
Bibbidi Bobbidi Boutique - Magic Kingdom, so I made a note of that reservation time. On our last trip, I made a note of our Caring for Giants tour.
Anne, before or after dinner at T-REX™, I do hope you have some time to explore Disney Springs. The shops are amazing!
Magic, memories and Minnie Mouse hugs,
Donyell
