You'll need to have checked into the festival through Pokémon Go, so you can't profit from having sold your ticket to someone else. You'll also need to show receipts if you paid more than $107 in expenses. And if this is like many class action lawsuits, we wouldn't count on a large payout given the scale of the case and the usual lawyers' fees.

That's still more compensation than guests received in 2017, however. And for Niantic, it's a lesson learned. The company is now keenly aware of the problems Pokémon Go's massive scale can bring, and it's now focused more on Community Days and other gatherings that are less likely to cause havoc.
