WorldCon 2025 seattle

So its my birthday and im coming down to seattle for it and it happens to line up with the days worldcon is in town. ive been researching all day but im not really seeing sufficent info on whats really happening there. So i have a few questions.

1:who are the popular panalists i might know? i saw on the site grrm was going to be there but then when i look up healiners it doesnt say anything about him so im a little confused.

2:where do i see what time people are where?

3:whats happening besides panals?
