Swan/Dolphin question

[satchel01]

If I were to book a room through Expedia at the Swan or Dolphin, how would Genie know I was staying there? In other words would I still be able to book lightning lanes starting at 7am?

I would assume you would have a reservation number to enter into the MDE app which would allow you to book Genie+ reservations based on your tickets and park reservations.
