Saturday's in May

I normally go to Cedar Point on weekdays in June or July but my schedule will not allow me to do it this year so I have to go on the weekend. I have never been to CP on a weekend in May and I'm going with a few friends from Texas who have never been to CP before, how does the crowd compare on a weekend in May vs. a weekday in June or July assuming its a decent day outside?
