Here is some more info about the aforementioned raffled seats for the main event.

One seat will be raffled at the close of registration of each flight, meaning there will be six seats raffled over the entirety of Day 1. There will also be six more seats raffled at the start of Day 2 on Sunday.

Players will be given one raffle ticket for each entry and re-entry. And if the player happens to bag a chip stack they will get an additional raffle ticket.
One bonus ticket for early bird registration.

Players must be present to win their raffle seat and may only win one seat per player.
