I'm sure that someone, somewhere has a list of the movies that they show. Knowing Disney, those movies don't change very often.
Peter Pan is the other ride that has a very long line even as late as after the fireworks.
I think if your party tickets are linked to your
MDE account then they become clones of your account. This means that if you book fastpasses for that day with your regular tickets then you won't be able to book fp+ using the party tickets, since no one can book more than three fp+ ahead of time, no matter how many tickets you have.
So I would think that if you want to do both, use your park tickets for fp+s and book fp+ using your party tickets, then you would have to create phantoms on your MDE account or a new MDE account for the party tickets. You would have to use new names if you want a new account. If Disney sees the same name then it will merge the accounts.
