We're going May 10th-21st. Past years we've gone the same exact time (but the dates change obviously). We've never waited longer than 10 minutes. However our last day, Saturday, things change from 10 minute waits to 90 minute waits. The southern schools get out and it seems like they all head toward Disney. I mean, it's still much better than July and August, but it's nothing like the beginning and middle May. We couldn't believe the change 1 day made. Hope that helps.
