Which day is a better day to go to pki? A weekend in May or a weekday in August?
Well for my 2 cents. I've always gone during the week in June, but if I were to harbor a guess, I'd say May would be your better choice. Sure the park is open longer in August, but frankly there are a lot more people vacationing in August than in May. As I said this is just my opinion so you can take it for what it's worth. :-)
