Welcome to planDisney, Weikeng! Thanks so much for coming to us with your question today.
I totally admire your out-of-the-box thinking, and I award you full points for imagination and creativity. The answer here is pretty straightforward: Walt Disney World only allows one form of admission per guest per day, so unfortunately, you wouldn't be able to use both an
Annual Pass and a 1-day ticket simultaneously for the same person.
Each person can only have one active
park reservation per day, and the
My Disney Experience app is designed to enforce that. If you tried to assign both tickets to yourself, the system would prevent you from holding two theme park reservations for the same date, because it sees you as one person. That means that the option to book two separate
Lightning Lane Multi Passes as if you were two people isn't possible, even with multiple forms of valid admission.
The system is really built around one person = one ticket = one set of Lightning Lane selections. So while it might sound like a great hack to double up and maximize your ride time, your best bet is to stick with the Lightning Lane Multi Pass you're eligible for and make the most of it! With a good strategy, like booking high-demand attractions early and checking for rolling return windows, you can still experience a whole lot of magic without even considering a second ticket.
I hope this helps clear things up, and if you have any other trip-planning questions, we're always here to help!
