As @Nick said, you’ll be in a mass of people, so you’ll just have to go with the flow. I detailed our experience back in August of last year if you’d like to see some examples of what it looks like.
FWIW: Since it was such a new thing for everyone I included a map of our timing for others’ reference, but as it appears our day was an especially long slog into the ride, so current waits if you are at front of pack should be shorter.
