I survived! I fell behind at Pioneer Place and bounced off the waterfront and back, then was going to try Lloyd center until I found my half of the group. I learned two things the hard way today. 8P
Lesson 1: take only one cosplay. Whatever you take with you, you will lug through pouring rain and blazing sun all day long, and it takes you longer to get ready to move to another area.
Lesson 2: carry a cell phone with you! It helps when you're lost and you have a way to call one of the people and find them again.
