How busy are Sept extra magic hour days?

[disneyjenca]

I'm trying to decide whether to take advantage of or avoid extra magic hour days for my trip in mid-September. Any thoughts/experiences?

Thanks!

I will be there in mid-september and plan on avoiding early entry days. I have found that since September has very low crowds, I dont need that extra hour. The parks do seem more crowded on early entry days. (keeping in mind that it still doesnt compare to other times of the year)
