Crowds on Sunday 8/26

I have family coming in for a trip on Sunday August 26, what do you think the crowds will be like and should I get Fast Lane? I never go on Sundays especially at this point of the year so I don't know what it's like.

Hours Aug. 26 are 11-9, and the Sandusky schools open the next day.\

Early entry should be 10.

Crowds could go either way.

Theres going to be over 1 million people there just that day. :)

At least! :)

The hours of 11-9 would suggest that this is historically a lighter crowd day.

How were they?
