Confused about No Kings protest

I want to attend the main Seattle No Kings protest on October 18. I went to the No Kings website and they show one at Capitol Hill at 10am and another at Seattle Center at noon. Are they connected? Which is the main one? The first No Kings protest (in June) started at Cal Anderson and marched to Seattle Center. But that doesn’t seem to be the plan this time, the website for the Seattle Center one says the march starts there at 1pm. Does anyone have more info? Thank you!
