Disneyland May 24 Open 24 Hours Question

[DisneylandClub]

You already know I'm going! Lol but I have a question, are the tickets on presage online? Or can I just show up without worrying about the tickets being sold out? It opens. From 6 am to closes at 6 am. I plan on showing up before 6 am lol
So thanks, because if I show up early only to find out the tickets are sold out, I'll be upset thanks in advanced
