What are wait times like for meeting Merida just before the Parade or just after the parade?
I don’t know the answer to your question. I can tell you that Merida is only out for about 30-40 minutes before she takes abreak for 30 min. The CM that works there told us that many times, they have to close the line so that Merida can get to her break.
Try lining up before she comes back, so you will definitely get to see her in her next set.
Hope that helps.
