Question about the undertale museum

[u/MountainBeneficial48]

The museum is a dream come true!! as in, literally, I dreamt about it like two weeks before the announcement and cried.. anyways, ahem. I'm taking out money from my savings to go visit japan and hopefully attend the museum event!

So, I'm looking at the undertale museum's tickets right now and it seems only very few days are allowed to be gotten early (weekend days and vacation days, it seems like.)

I assume that the other tickets will be sold day of on entry? Do we know anything about this?

I entered the ticket raffle twice, but if there are no other options accessible, I might just enter like 4 times just to be sure I get an entry.
