If I get the residents year tickets for tomorrow, can I use it? Tomorrow is Easter Day.

I think IT dosn't aply on holly days But you shoul call tomorrow morning

It dependson the ticket, there's one of 175 days by 150 dollars I guess but that one is for low seasons of tourism, that one is mostly for people that live in Los Angeles and near areas

I thinl what you could do is buy the ticket for tomorrow and then when you get inside you can go to customer service and upgrade your ticket to the pass. Then you would be good regardless.

You should be able to, but I would check the black out dates that you can get when you download the app which will tell you not only those but also have a map of the theme park, hours of operation, but also show times.
