Darth's Mall Wait Times

Are the lines to get into Darth’s Mall always long on Star War’s weekends? Thinking about planning a trip for next May so we go to a Star Wars Weekend. All the youtube videos show really long lines for the Mall. Is that just the first day? Or first weekend? Or all of the weekends? Does the line get shorter at the end of the day?

Also, there is a “less” crowded weekend to go in general?
