How its her favorite ride but you're unaware of how the wait time works. Not trying to sound rude just genuinely curious.
Its not listed on the app because it does not have a standby line.
Just like you won't find a wait time for Tiana's Bayou Adventure at Magic Kingdom because it too does not have a standby line.
It has a
Lightning Lane line and a Virtual Queue line.
You can purchase a Lightning Lane Single pass for it 7 days prior to check in if staying onsite or 3 days prior to your park day if not staying onsite.
You can also try for the Virtual Queue day of a 7am and 1pm and if you are staying in a deluxe resort and going to the extended evening hours at EPCOT on a Monday you can try for it at 6pm.
If its a must do then I suggest Lightning Lane Single Pass.
